Abstract
The frequency intervals of localization of the bands of the characteristic and noncharacteristic vibrations of 5-substituted pyrimidines were determined on the basis of calculations and analysis of the experimental data. A theoretical interpretation of the bands with respect to the form of vibrations is given, and the groups of characteristic and noncharacteristic vibrations of the aromatic skeleton of 5-monosubstituted pyrimidines were established. Groups of substituents with different regions of localization of the frequencies of the aromatic skeleton were isolated for the noncharacteristic vibrations.
