Effect of dipole-dipole intermolecular forces in the vibration spectra of organic compounds

I. Effect on Frequency: Theoretical Discussion
  • A. V. Sechkarev


The potential energy of a polar liquid is derived from the electrostatic interaction of point dipoles, taking into account the formation of local groups with short-range order with minimum energy. The methods of classical mechanics are used to estimate the effects of interaction on the normal vibration frequencies. It is shown that interaction increases the frequencies of low-frequency dipole-rotation vibrations; frequencies of other types may increase or decrease.
