| Abstract: |
The infrared and
Raman spectral studies and the normal coordinate analysis of aminobenzoesaeure
(AB) have been presented. The Fourier Transform Infrared spectrum has been
obtained in the region 4000-400 cm-1 and the FT-Raman spectrum has been
recorded over the range 3500-200 cm-1. The spectra have been investigated
in terms of various fundamental modes of vibration. The observed infrared and
Raman spectra exhibit all the salient features reported in literature. Accuracy
of the spectral line positions and their bandwidths are found to be
satisfactory. The structure of the complex has been established on the basis of
CS symmetry. A normal coordinate analysis has been carried out
following Wilson’s
F.G.matrix method and a systematic set of potential constants has been
evaluated. To check whether the chosen set of symmetric coordinates contribute
maximum to the potential energy associated with the molecule, the potential
energy distribution (PED) has been carried out.
