On the use of ultraviolet resonance Raman intensities to elaborate molecular force fields: application to nucleic acid bases and aromatic amino acid residues models.
Normal modes analyses for different molecules with biological interest have been performed and checked via the calculation of resonance Raman intensities. For this purpose, molecular orbital calculations were used to determine bond order changes in the lowest-lying electronic transitions. These bond order changes were used to calculate resonance Raman intensities in order to obtain correct vibrational assignments and reliable force fields.
