Raman and FTIR spectra of 2,4,5- and 3,4,5-tri-fluoro-benzonitriles have been recorded in the regions 50-4000 cm(-1) and 400-4000 cm(-1), respectively. Measurement of depolarization ratios for the Raman lines has also been made. Optimized geometrical parameters, charge distributions and vibrational wavenumbers were calculated using ab initio quantum chemical Gaussian 03, Revision C.02 software. Each vibration has been assigned using observed wavenumbers in the IR and Raman spectra and their… CONTINUE READING
