Abstract
Possibility of intermolecular hydrogen bonds formation in associates of pentyl ester of p-(N-α-D-glucopyranoside)aminobenzoic acid was studied. In order to reveal the features of hydrogen bond system in H-complexes being studied the comparative analysis of experimental and theoretical IR spectra of dimer molecules was carried out. The assessment of interaction energy between two molecules and its decomposition by Morokum’s method was also given. It was found that the predominant contributions in the interaction energy were electrostatic and exchange repulsion terms. According to the obtained data, the cyclic form of glucose residue leads to low probability of associate formation.

Keywords: liquid crystals, hydrogen bonds, simulation
