Laser Raman and Infrared Spectroscopic Studies on 5-Methyl Cytosine

Abstract

The laser Raman and infrared spectra of 5-methyl cytosine have been recorded on a Cary model 82 grating.spectrophotometer with an argon laser source and Perkin-Elmer 983 double beam grating spectrophotometer respectively. The spectra have been analysed on the basis of fundamentals, combinations and overtones and the frequencies have been assigned to various modes of vibration assuming C_s point group symmetry. Further based on the present assignment, a complete vibrational analysis has been carried out for this molecule and the results are briefly discussed.
