VIBRATIONAL-SPECTRA OF 2-AMINOPYRIMIDINE, ASSIGNMENTS AND ITS NORMAL-COORDINATE ANALYSIS

The laser Raman and Fourier transform infrared spectra of 2-aminopyrimidine were recorded in the range 4000-100 cm-1 and 4000-500 cm-1 respectively. The observed frequencies were assigned to various modes of vibrations in terms of fundamentals and combinations by assuming C, point group symmetry. A normal coordinate analysis was also carried out using general quadratic valence force field. A complete vibrational analysis is presented here for this molecule and results are briefly discussed.
