Abstract

The density functional theory method B3LYP / 6-31G (d) was used to simulate the structure and vibrational spectra of dimers of dihydroxybenzoic acid molecules: the minimum energy, geometric structure, components of the dipole moment, frequencies of normal vibrations, and their intensities in the IR spectrum were calculated.
