摘要
New results of investigations on the molecular structure of canonic bases of uracil and thymine are given. Using theoretical calculations it is shown that increase of band numbers in the range of CO stretching vibrations of the high-resolution IR spectra and uracil and thymine may be due to the existence of the different conformations of these compounds. IR spectra and the structure of hydrates and selfassociates of cytosine isolated in Ar matrices are also studied. Keto-enolic equilibrium is shown to shift to the keto-form on the intermolecular interactions in the matrix. © 1990.
