Повний текст джерелаThe combination of broadband spectroscopic methods allows a comprehensive view of the electronic system of molecules in the excited state. On riboflavin in acidic environment the proton-transfer is observed with transient absorption and -flurescence in the S1-state. With transient absorption and femtosecond-stimulated Raman-spectroscopy the population transfer into the electronic ground-state is followed and characterized.

Повний текст джерелаMaterials that exhibit giant dielectric properties have received a huge amount of attention from the scientific and industrial communities due to their potentialities and applications in technological devices, in particular for microelectronic applications. In this work, we are interested in studying the vibrational properties of a prototypical relaxor single crystal, PbMg1/3Nb2/3O3 (PMN), as well as nanoceramics of SrTiO3 (STO) with controlled grain sizes. The experiments have been mostly performed by hyper-Raman scattering (HRS), an original non-linear inelastic light scattering spectroscopy. Special attention was devoted to low frequency vibrations, and structural models were developed to relate the vibrational signatures to the giant dielectric responses of these systems.HRS spectroscopy was pushed towards its limit and provided a comprehensive picture of the polarization dynamics of PMN in the THz-range within the whole temperature sequence of its characteristic relaxor states. The widespread hypothesis of two paraelectric soft modes is convincingly excluded. The observation of the split ferroelectric mode reveals the local anisotropy below about 400 K. In contrast, the spectral anomalies observed at higher temperatures are explained as due to avoided crossing of the primary polar soft mode with a temperature-independent, non-polar spectral feature. The temperature changes of the vibrational modes involved in the measured fluctuation spectra of PMN were captured in a simple model that accounts for the temperature dependence of the dielectric permittivity as well.On the other hand, HRS experiments were carried-out on STO single crystal and nano-ceramics of different grain sizes, 80nm and 150nm. Contrary to IR-absorption which gives an effective spectral response of the core and the shell(s) constituting the grains, we show that hyper-Raman provides information of the individual core and shell responses. The spectral analysis reveals that except from their volume, the grains in the two ceramics exhibit very similar structures and properties: same value and temperature dependence of the shell thickness surrounding the core, and same dielectric response of the core as well as of the shell in the two samples. Structural models relating the vibrational properties to the effective dielectric permittivity were developed, and confirm that in STO the grains are composed by one core and two surrounding shells. We demonstrate that between 150 nm and 80 nm the decrease of the effective dielectric permittivity with grain size relates mostly to a change in core and shell volume fraction

Повний текст джерелаOf all greenhouse gases (GHGs), carbon dioxide is definitely the most notorious to the wide public. Yet, there are GHGs present in much more tiny amounts in the Earth’s atmosphere, whose destructive power is substantial albeit less widely publicized. SF6 is a GHG considered as a dangerous pollutant of our atmosphere for that its global warming potential (GWP) amounts to about 24 000 times the GWP of CO2. Of anthropogenic origin, primarily owing to the industry of electrical insulators, the emissions of that gas are presently being increased at the alarming rate of 8% per year. These observations fully justify why sulfur hexafluoride currently tends to become a serious competitor of carbon dioxide and why its emissions are targeted in the Kyoto protocol. Here we present a study, both experimental and theoretical, of certain weakly-allowed Raman-scattering transitions related to gaseous SF6. These are either transitions in the isolated molecules or collision-induced transitions within pairs of molecules. Specifically, the overtones 2ν3 and 2ν5 of SF6 were studied, which both are Raman-active because of electrical or mechanical anharmonicity in the isolated molecule. This choice was prompted by the fact that ν3 and ν5 are the molecule’s most representative stretching and bending vibrations, respectively. It follows an experimental study of the collision-induced SF6−SF6 transition at the position of the ν3 vibration, as well as other transitions related to the isolated molecule. The high-sensitivity Raman equipment we have used and the stiff protocol we have followed regarding detection, acquisition, processing and analysis of spectra are part of a long experience and knowhow within a research group recognized for its capacity to capture and analyze extremely weak light signals

Повний текст джерелаCe travail traite de la transposition de cette technique habituellement appliquée à l'étude des modes propres de vibration de nanoparticules solides à la recherche de modes similaires chez leur équivalent biologique, les virus.
Nous revenons dans un premier temps sur les expériences Brillouin (ou Raman basse fréquence) sur des verres dopés à l'or et discutons de l'utilité du tandem Fabry-Pérot en particulier par l'apport de la haute résolution dans la détection des levées de dégénérescence associées à l'anisotropie des paramètres élastiques des nanoparticules d'or facettées.
La deuxième partie de ce travail est consacrée à la recherche de modes de vibration d'ensemble sur des virus à morphologie sphérique à travers l'étude de différents types d'échantillons : solutions, couches bidimensionnelles et cristaux tridimensionnels de virus. Cette partie rend compte d'une première détermination des constantes élastiques globales d'un cristal de phytovirus. Alors que pour les virus de petite taille (15-30nm) aucune preuve indiscutable de l'existence d'un mode de vibration de virus n'a pu être trouvée, pour un virus de plus grande taille (environ 200nm), un signal s'apparentant à un mode de vibration de virus a été observé.
