title: [Infrared spectra of associated and hydrated pyrimidine bases of nucleic acids in argon matrix].
abstract: The spectral characteristics of interacting pyrimidine bases of nucleic acids--cytosine, 1-methylcytosine, uracil in autoassociates and hydrates--are investigated using the high-resolution infrared spectroscopy in argon matrices. Shifts of vibration frequencies in simple complexes are stated to be from 10 to 30 cm-1 in the 4000-400 cm-1 region observed. The isolated state-solid phase transition is followed by the absorption maximum shift, the latter being some hundreds of cm-1 in the 4000-2000 cm-1 region and some tens of cm-1 in the 1800-400 cm-1 region.
