Abstract

IR-spectra of disodium riboguanosine 5'-monophosphate (5'-GMP-2Na+) films in 900-1800 cm-1 range at 0-96% relative humidity are obtained. The centres and the hydrational level of the nucleotide are determined by analysis of frequencies and intensities of the absorption bands. The sorption of about 8 water molecules is found to lead to crystallization of 5'-GMP-2Na+. The calculation of resonance interactions showed that the crystal structure corresponds to the telramer model. The quantum-chemical calculation of electronic density evidences that observed spectral changes at wetting of 5'-GMP-2Na+ films can be explained qualitatively by the effect of hydration and influence of cations.
