FT-IR and FT-RAMAN investigations of nicotinaldehyde

The Fourier transform Raman and infrared spectra of nicotinaldehyde were recorded and the observed frequencies were assigned to various modes of vibration in terms of fundamentals by assuming Cs point group symmetry. A normal coordinate analysis was also carried out using a simple valence force field. A complete vibrational analysis is presented here for this molecule and the results are briefly discussed.
