The Fourier transform Raman (FT-Raman) and infrared absorption (FTIR) spectra of form II poly(vinylidene fluoride) have been recorded and analysed. A complete spectral analysis, assignments to observed bands, normal coordinate analysis and discussion of the spectra are presented. The computed spectrum is in excellent agreement with experiment. The potential energy distribution (PED) is evaluate...

We synthesized poly(isothianaphthene methine)s with chiral alkyl chains in the substituent. Resultant polymers are soluble in THF and CHCl₃. Structure of the polymers was characterized with FT-IR, FT-Raman, and UV-Vis-NIR optical absorption spectroscopy. They showed low-bandgap both in solution and in a form of film. Optical activity of the polymers was confirmed with optical rotatory dispersio...

FT-IR and FT-Raman spectra of 2-phenyl-4H-3,1-benzoxazin-4-one were recorded and analyzed. The vibrational wavenumbers of the title compound have been computed using the HartreeFock and B3LYP levels of theory using 6-31G* basis set and compared with the experimental data. The results indicate that B3LYP calculations approximate the observed fundamental wavenumbers much better than the HF result...

Abstract: This paper reports the reaction of cotton cellulose with sulphamic acid using pad bake process. FT-IR and FT-Raman were used to analyse the intermediate products formed during this study. The self-crosslinking of the modified cotton fibre has special characteristics including good dye ability in case of ammonia or ethanolamine initiated crosslinking. Peroxide should react with the mod...

The biochemical changes on normal and degenerated tissues of rotator cuff supraspinatus tendons were probed by FT-Raman spectroscopy. The Raman spectra showed differences on the spectral regions of cysteine, amino acids, nucleic acids, carbohydrates, and lipids. These spectral differences were assigned to pathological biochemical alterations due to the degenerative process of the tendon. Princi...

The European project FAIR-CT96-5053 concerned the application of the FT-Raman and infrared spectroscopy in food chemistry and quality control. Our research mainly concerned the study of the potential of Raman spectroscopy and the comparison with the results achieved in infrared spectroscopy. The discrimination of virgin olive oil from other edible oils, and the detection and quantification of v...

Fourier transform infrared and Raman spectra of poly vinyl acetate and its deuterated derivative were recorded and observed frequencies were assigned to various mode of vibration in terms of fundamentals and combinations by assuming Cs point group symmetry. A normal coordinate analysis was also carried out using simple valence force field. A complete vibrational analysis is presented here for t...
