Abstract: The model calculations of possible uracil dimmers vibration spectra by density functional method done. The intermolecular interaction mechanism have been by using ab initio quantum calculations of geometrical parameters and adiabatic potentials proposed.

Keywords: vibrational spectra, anharmonic approximation, adiabatic potentials.
