Abstract:
The properties of water vapor have been studied. The main attention is focused on the physical nature of the effective polarizability of water vapor and the heat capacity of water vapor at a constant volume, with a proper modeling of those parameters being a good test for a correct description of the dimer concentration in various approaches. Thermal vibrations of water dimers are found to be the main factor governing the specific temperature dependences of those characteristics, and the normal coordinates of dimer vibrations are determined. Fluctuations of the dipole moments of dimers and their contribution to the dielectric permittivity of water vapor are considered in detail. The contribution of the interparticle interaction to the heat capacity is taken into account. By analyzing the effective polarizability and the heat capacity, the temperature dependence of the dimer concentration at the vapor-liquid coexistence curve is determined. The noticeable dimerization in saturated water vapor takes place only at temperatures T/Tc > 0.8, where Tc is the critical temperature.

Abstract:
Abstract Molecular dynamics simulations were used to explore the distribution of linkages in coumaryl alcohol and coniferyl alcohol systems, including monomeric systems and monomers interacting with β-O4 dimers, respectively. Studying the interactions of two monolignols and the corresponding dimers sheds light on the preferred mechanism of reaction of the growing lignin polymer from the view of kinetic factors. The energy change upon association was quantified, and the distances between the centers of mass of different molecules, and the relative orientations between the phenol groups were calculated for all the systems. Using a cut-off threshold of 4 Å to indicate association leading to bond formation, it is concluded that the presence of the additional methoxy group on coniferyl alcohol assists in promoting interaction of the O4 group with the second moiety. Based on the computed data it is furthermore concluded that in aqueous solution, the most likely model of polymerization is that involving initial dimer formation, followed by dimer-dimer association.

Abstract:
New aspects of the theory of ideal associated mixtures related to a differentiation between formed cyclic and linear dimers are discussed. A mathematical analysis is presented for the dimerization model, A + B + A2, the continuous association (Mecke–Kempter) model, [Formula: see text], both coupled with the cyclic dimmer → linear dimer transformation and for the unsymmetrical (mixed) dimer formation model, A + B + A2 + B2 + AB. Introduction of the standard reaction enthalpies and volumes associated with transformations of dimers leads to a considerable change in behavior and symmetry properties of the excess thermodynamic functions. In terms of the modified Mecke–Kempter model, a consistent representation of the excess Gibbs energy of mixing GE, heat of mixing HE, and excess molar volume VE is reported for the acetic acid – water system at 298.15 K. Key words: association, dimerization, linear dimers, cyclic dimers, hydrogen bonding, carboxylic acids, alcohols, aqueous solutions.

Abstract:
The ternary title complex (2) is readily obtained by co-crystallization of 18-crown-6 (18C6) and di(4-carboxybenzenesulfonyl)amine (1) from hot water and was characterized by low-temperature X-ray diffraction. The crystal structure (triclinic, space group P1̄) displays one-dimensional polymeric sequences [(H2O)2···18C6···(H2O)2···{HN(SO2C6H4-4-COOH)2}2] in which the molecules are associated through seven independent hydrogen bonds. The 18C6 ring lies on a crystallographic inversion centre and adopts the common pseudo-D3d conformation. On both sides, the ring is flanked by a strongly hydrogen-bonded water dimer H2O-H-OH. This species forms three weak O-H-O bonds to alternating ether oxygen atoms and accepts a strong N-H-O bond from the adjacent acid dimer (1)2. The water dimers thus act as ideal donor-acceptor balancing links between the hexafunctional polyether and the monofunctional NH groups of the (1)2 dimers. The (1)2 dimer itself is formed by two symmetry related cyclic O-H···O interactions (both H disordered) of the well-known carboxylic acid dimer type. To this effect, molecule 1 adopts a folded, pseudo-Cs symmetric conformation with stacked carboxyphenyl groups.

Abstract:
This study aims to investigate the effect of different wavelengths (254, 266, 280 and 365 nm) in polychromatic medium-pressure (MP) UV radiation on the ability of photolyases in repairing dimers and discusses its impact on subsequent photoreactivation. Photolyase was exposed to various doses and irradiances of the UV wavelengths and the dimer repair abilities of the irradiated photolyase were determined via a spectrophotometric assay. At wavelengths below 300 nm, dimer repair rates were not influenced by the UV irradiation between 0.03 and 0.10 mW cm−2. For 365 nm, photolyase exhibited enhanced dimer repair at 0.05 mW cm−2 and then reduced dimer repair with increasing irradiance. In addition, photolyase was found to have decreasing dimer repair rates when exposed to increasing UV doses at all tested wavelengths. Lower photoreactivation levels after MP UV disinfection as compared to low-pressure (LP) UV disinfection was not attributable to a single wavelength in the polychromatic radiation, but is possibly due to the simultaneous exposure of photolyase to a broad spectrum of radiation, which led to a reduction in the dimer repair ability of photolyase. This study is the first to report the direct effects of UV radiation on photolyase enzyme. The data in the study provide some evidence for the mechanism for which MP UV disinfection suppresses photoreactivation in Escherichia coli, which has only been speculated on so far. The knowledge from this study will provide a basis upon which to investigate other enzymes involved in the repair of UV damage to DNA.

Abstract:
Abstract. Laboratory measurements of water vapor absorption using cavity ring-down spectroscopy revealed a broad absorption at 405 nm with a quadratic dependence on water monomer concentration, a similar absorption with a linear component at 532 nm, and only linear absorption at 570 nm in the vicinity of water monomer peaks. D2O absorption is weaker and linear at 405 nm. Van't Hoff plots constructed at 405.26 nm suggest that for dimerization, Keq=0.056±0.02 atm−1, ΔH°301 K=−16.6±2 kJ mol−1 and ΔS°301 K=−80±10 J mol−1 K−1. This transition peaks at 409.5 nm, could be attributed to the 8th overtone of water dimer and the 532 nm absorption to the 6th overtone. It is possible that some lower overtones previously searched for are less enhanced. These absorptions could increase water vapor feed back calculations leading to higher global temperature projections with currently projected greenhouse gas levels or greater cooling from greenhouse gas reductions.

Abstract:
Abstract. Absorption of solar radiation by water dimer molecules in the Earth's atmosphere has the potential to act as a positive feedback effect for climate change. There seems little doubt from the results of previous laboratory and theoretical studies that significant concentrations of the water dimer should be present in the atmosphere, yet attempts to detect water dimer absorption signatures in atmospheric field studies have so far yielded inconclusive results. Here we report spectral measurements in the near-infrared around 750 nm in the expected region of the | 0〈f | 4〉b|0 〉 overtone of the water dimer's hydrogen-bonded OH stretching vibration. The results were obtained using broadband cavity ringdown spectroscopy (BBCRDS), a methodology that allows absorption measurements to be made under controlled laboratory conditions but over absorption path lengths representative of atmospheric conditions. In order to account correctly and completely for the overlapping absorption of monomer molecules in the same spectral region, we have also constructed a new list of spectral data (UCL08) for the water monomer in the 750–20 000 cm−1 (13 μm–500 nm) range. Our results show that the additional lines included in the UCL08 spectral database provide an improved representation of the measured water monomer absorption in the 750 nm region. No absorption features other than those attributable to the water monomer were detected in BBCRDS experiments performed on water vapour samples containing dimer concentrations up to an order of magnitude greater than expected in the ambient atmosphere. The absence of detectable water dimer features leads us to conclude that, in the absence of significant errors in calculated dimer oscillator strengths or monomer/dimer equilibrium constants, the widths of any water dimer absorption features present around 750 nm are of the order of 100 cm−1 HWHM, and certainly greater than the 25–30 cm−1 HWHM reported in the literature for lower energy water dimer transitions up to 8000 cm−1.

Abstract:
ABSTRACT Pertussis toxin (PT), a holomer consisting of a catalytic S1 subunit and a B oligomer composed of S2-S4 and S3-S4 dimers, held together by the S5 subunit, exerts profound effects on immune cells, including T-cell mitogenicity. While the mitogenic activity of PT was shown to reside fully within the B oligomer, it could not be assigned to any particular B-oligomer component. In this study, we purified the S3-S4 dimer to homogeneity under conditions propitious to maintenance of the native conformation. In contrast to previous reports which suggested that both S3-S4 and S2-S4 dimers are necessary for mitogenic activity, our preparation of the highly purified S3-S4 dimer was as strongly mitogenic as the B oligomer, suggesting that the S3-S4 dimer accounts for the mitogenic activity of the B oligomer. Moreover, in vitro stimulation of naive lymphocytes by the S3-S4 dimer resulted in reversal of the normal CD4+/CD8+ T-cell ratio from approximately 2:1 to 1:2. The reversal of the CD4+/CD8+ T-cell ratio is unlikely to be due to preferential apoptosis-necrosis of CD4+ T cells, as indicated by fluorescence-activated cell sorter analysis of annexin-stained T-cell subsets, or to preferential stimulation of CD8+ T cells. The mechanism underlying the reversal requires further investigation. Nevertheless, the data presented indicate that the S3-S4 dimer may have potential use in the context of diseases amenable to immunological modulation.

Abstract:
In this paper, we study the electronic and ionic dynamics of the water dimer subject to short and intense laser pulses. The dynamics is described by means of the time-dependent local-density approximation coupled to ionic molecular dynamics (TDLDA-MD) non-adiabatically. The impact of laser frequency on the response of water dimer is discussed by exploring the ionization, the dipole signal and bond lengths of water dimer. Furthermore, it is found that the water donor is more sensitive to the laser field than the water acceptor and the probabilities for the ionic states show the general pattern of the typical sequence of the interlaced production maxima.

Abstract:
The energy band structures of a cytosine, adenine, and guanine stack in the presence of water have been calculated by the ab initio crystal-orbital method. The surrounding water molecules have been simulated by arrays of point charges, using for their positions the results of previous Monte-Carlo calculations of the corresponding polynucleotides. Furthermore, the effects of internucleotide interactions have been studied on the basis of calculations on base dimer stacks in comparison to the corresponding dimers and monomers.
