ResumoUltraviolet resonance Raman spectra (266-nm excitation) were studied for adenine, uracil and thymine derivatives in several solvents at low concentration (0.5−10 mM) where hydrogen bonding between solute molecules is negligible. The Raman spectra patterns depend critically on the proton-accepting/donating properties of the solvents. Raman bands which show large solvent effects are expected to be useful in studying the hydrogen-bonding states of the nucleic acid bases.
