Vibrational Raman spectra of some substituted uracils
Vibrational assignments of the frequencies of 6-azauracil, 5-fluorouracil, 5-bromouracil and 6-azathymine have been made with the help of their Raman and infrared spectra. Raman spectra of these molecules were recorded in the range 75–4000cm-1. The near infrared spectra of these molecules were also recorded in the 400–4000cm-1 range using the nujol mull technique. The vibrational frequencies have been noted and the vibrational assignments have been made on the basis of the group frequency approach. The assignments have also been facilitated by comparison with the frequencies of similar molecules.
