The frequencies and relative intensities of lines in the Raman spectra of the condensed states of guanine and its deutero substituted analog have been calculated. The effect of hydrogen bonding on the Raman spectrum has been studied. Guanine exists in different tautomeric forms (G-N9H and G-N7H) at different pH in aqueous solution (for acidic and alkaline media, respectively).
