Full textDans l'etude suivante, l'observation de nouvelles bandes d'absorption de hcn et de leurs bandes chaudes associees nous a permis de determiner la principale constante d'interaction de fermi couplant les modes d'elongations de la molecule. Pour ocs, une analyse detaillee des perturbations via les intensites des bandes vibrationnelles a valide le modele global d'hamiltonien utilise, base sur la theorie des modes normaux. Des moments dipolaires induits de l'ordre de 10 7 debye ont ete determines. Par ailleurs, deux molecules silicees ont ete etudiees. Dans le cas de sihf 3, une analyse rotationnelle ainsi qu'une etude des couplages des niveaux vibrationnels ont ete realisees. Les resultats sont compares aux predictions ab initio. Enfin, dans le cadre d'une etude globale des bandes harmoniques de la vibration si-h dans h 3sid, impliquant des spectres a transformee de fourier ainsi que des calculs ab initio, nous avons observe la 5 i e m e bande harmonique et analyse sa structure a l'aide de la theorie des modes locaux. Nous avons mis en evidence la degenerescence vibrationnelle des niveaux (600,a 1) et (600,e), et observe au niveau de la structure de rotation la perte de symetrie de la molecule

Full textThe ammonia molecule is one of the most abundant species in the atmosphere of solar planets and isotopic ratio 14N/15N is an important parameter to measure. Spectroscopy of ammonia was recently updated for 14NH3 by Sung et al [JQSRT, vol. 113, 11,1066 2012] in the range 6300-7000 cm−1 and included in HITRAN 2012 database.For the 15NH3 isotopologue, Lees et al [JMS, 251, no. 1-2, 241–251, 2008] assigned some transitions belonging to ν1 + ν3, ν1 + 2ν4 et ν3 + 2ν4 in the range 6412 to 6819 cm−1.Furthermore few line positions and strengths of transitions have been measured by Linsand al [App.Phy. B,102, 293–301, 2011.] with the goal of isotopic ratio measurement. In our work the spectroscopy of 14NH3 and 15NH3 have been extended with the help of an External Cavity Diode Tunable Laser spectrometer (ECDTLS) in the range 6369 to 6578 cm−1 and recordings at four temperatures (150K, 180K, 220K,296K).The spectra has been calibrated and each transition fitted to Voigt profile. Lines positions and strengths have been measured. The intensity ratio temperature dependence have been used to derive the energy of lower state for each transition. A specific treatment has been developed considering pairs of transitions intensities removing pressure dependence.For 14NH3 a transition list has been proposed including line position, strength and lower stateenergy. Compared with Sung et al 's work, the knowledge is increased by one third. For 15NH3 compared to the Lees et al 's work (240 lines), a line list including position and strength for 2604 transitions at room temperature has been proposed for the first time

Full textThe pharmaceutical industry faces increasing regulatory pressure to optimize quality control. Content uniformity is a basic release test for solid dosage forms. To accelerate test throughput and comply with the Food and Drug Administration’s process analytical technology initiative, attention is increasingly turning to nondestructive spectroscopic techniques, notably near-infrared spectroscopy (NIRS). This thesis evaluate the potential of this spectroscopy for content uniformity on low-dosage tablets. The validation of NIRS using requisite linearity and standard error of prediction (SEP) criteria remains a challenge. This study innovatively applied wavelet transformation of the NIR spectra of a commercial tablet to build a model using conventional partial least squares regression and an artificial neural network. Wavelet coefficients in the PLS and ANN models reduced SEP by up to 60% compared to PLS models using mathematical spectra pretreatment

Full textThis document describes the design, realisation and characterisation of a time-resolved optical tomograph, using a femtosecond laser and a synchroscan streak camera. A study on cylindrical phantoms scattering the light has been carried out. Various mechanical scannings of these phantoms have been tested in order to de-tect the scattered light by transmission. A method making profitable the dimension of the slit to present the detection angle of the photons is also depicted. The setup performances are described in terms of temporal resolution, examination depth and acquisition time. Temporal profiles of photons detected thanks to this experimental arrangement have been used to produce both absorption phantoms' images and reduced scattering phantoms' images. Concerning the resolution of the direct problem, the algorithms used are based on the finite element method, while the resolution of the inverse problem, which is similar to an optimisation problem, re-quires an algebraic reconstruction technique. According to the methodology used, more absorbing and/or more scattering inclusions embedded in a phantom have been detected, based on the parameters mean time and integral intensity issued of the measured temporal profiles. With this tomograph, it is possible to measure mean times and integral intensities with an accuracy of ±3%, for a signals' acquisi-tion time higher than 10 minutes; this is only available if the scattering phantoms have a diameter lower than 4cm and a width of temporal point spread function lower than 3,5ns

Full textGelatin is a natural biopolymer obtained after denaturation and partial hydrolysis of collagen fibers, a fibrillar protein present in the connective tissues of all species of the animal kingdom. It is used in various industries, including the agri-food, pharmaceutical, photographic and cosmetic industries. Its functional properties depend on the manufacturing process, but also on the origin of the collagenous materials. The objective of this thesis is to characterize the raw material (pig rind), but also the gelatin obtained during the process, by a fast and non-destructive tool. The use of near-infrared spectroscopy coupled with chemometric methods allowed us to work on the scale of the laboratory but also on the industrial chain. The first study examines the heterogeneity of pig rinds, under laboratory conditions, in terms of protein, fat, moisture and collagen contents. Several models have been developed to predict these levels, from near infrared spectra collected on moving rinds. The best models have good performances. In the second industrial scale trial, an approach to gelatin yield from 75 tons batches was proposed. The predictive approach has not been conclusive; however, classification approaches have shown interesting results. The next two tests were on gelatin. The third test allowed the development of models for predicting the physicochemical properties of gelatin samples from near-infrared spectra, demonstrating very good predictive capabilities of these parameters (r²> 0.9). Finally, a final test allowed to link the molecular characteristics of the gelatin to its physicochemical properties, by the technique of Asymmetrical Field-Flow Fractionation coupled with a Multiangular Light Scattering Detector (MALS). The characterization parameters of AFlFFF-MALS make it possible to partially discriminate gelatin samples with different bloom and viscosity parameters
