The properties of purine and pyrimidine bases are determined by their hydrogen and π-bonding systems [1]. Past crystallographic studies [2] have indicated that halogen substitutents affect solid state base stacking patterns, and have suggested that stacking interactions involving the halogen substituents may contribute to the unusual physical and biological properties of nucleic acids which contain halogenated pyrimidines. Recent spectroscopic studies[3] of constitutents of nucleic acids have been motivated by their biological importance. Considering that the Raman spectroscopy in conjunction with IR spectroscopy offers many more possibilities to distinguish different symmetry species or to separate bands of close frequencies, we undertook the study of vibrational spectrum of 5-fluorocytosine(5-FC).
