IVANOV O. Мolecular structures and the thermodynamic parameters of the isomeric transitions of the dopant bioorganic molecules condensed in the low temperature inert matrices.

Objects: The dopant bioorganic molecules, nucleotide acid bases and aminoacids condensed in the low temperature inert matrices. Goals: the investigation of molecular structure and the thermodynamic of isomeric transitions of the dopant bioorganic molecules. Methods: FTIR matrix isolation spectroscopy, numerical calculations. New results: The original setup has been created for the quantitative measurements of infrared intensities and vibrational frequencies of the thermolabile bioorganic molecules in the low temperature matrices Kr, Ar, Ne. Using UV irradiation of the matrix samples, correlation between the molecular structures of isomers and the characteristic absorption bands was obtained. The equilibrium constants, enthalpy and entropy difference for the aminoacids and nucleic acid bases were determined.
