Influence of the H-bonding to the Structure and Vibrational Spectrum of 2,3-di-O-nytro-methyl-β-D-glucopyranoside

Structural-dynamic models of 2,3-di-O-nytro-methyl-β-D-glucopyranoside and its H-complexes were constructed by density functional method using the functional B3LYP in the basis 6-31G (d). Energies, structures, dipole moments, polarizabilities, frequencies of normal modes in harmonic approximation and IR intensities have been calculated. Interpretation of IR spectrum of the 2,3-di-O-nytromethyl-β-D-glucopyranoside and ethanol complexes is presented in range 600–3700 cm–1.
