*Geometric parameters and vibrational spectra of the trans- and gauche-conformers of the ethanol molecule were calculated using the B3LYP/cc-pVQZ and B3LYP/acc-pVQZ approximations. 2D potential energy surfaces for internal rotation of the hydroxyl and methyl tops were built. Kinetic parameters associated with torsion coordinates were calculated using Wilson’s*

**s***vectors at the same 2D grid nodes at which the potential energy values were found. Features of the kinematic and force interaction of the two tops were analyzed. Energies of torsion levels and frequencies of torsional vibrations of CH*...
