摘要：

A theoretical analysis of absorption spectra of uracil, thymine, and cytosine-nucleic acid bases-is carried out. Structural dynamic models of these molecules in their electronically excited states are constructed. On the basis of the calculated vibrational structure of the electronic spectra, different tautomeric forms of these molecules are determined. The possibility of modeling the influence of hydrogen bonds on the electronic-vibrational spectra is shown. (C) 2004 MAIK "Nauka/Interperiodica".
