внутримолекулярное взаимодействие Vibrational Spectra and Structure of Spinohromes Authors: El’kin M. D., Babkov L. M. Modeling calculations of geometric structure and vibrational spectra for spinazarin, ethylspinazarin, echinochrom is carried. Interpretaion of Vibrational State for Trinitrophenol Isomers and Conformers Authors: El’kin P. M., Umansky I. M., Dzhalmukhambetova E. A., Alykova O. M. On the base of modeling calculations of geometric and electronic structure for trinitrophenol the interpretation of vibrational spectra are propoused. Structural-dinamics Models and Spectral Identification of Monohydroxysubstituted Flavone Authors: El’kin P. M., Shagautdinova I. T., Pulin V. F. On based of the calculations for parameters of adiabatic potential by method DFT/b3LYP are proposed the structural-dinamics models for monohydroxyflavones. The indications of spectral identification are revealed.
