Potential functions of inversion of carbonyl compound molecules in the lower excited electronic states

The potential functions of the inversion of carbonyl compound molecules (al l molecules for which necessary experimental data were available) were dete rmined for the lower excited S-1 and T-1 electronic states with the use of various approximations. In addition to the model potentials with polynomial and Gauss-type barriers used earlier, calculations for Lorentz-type barrie rs were performed. The calculation results were analyzed to select the most reliable inversion potential functions for all molecules under study.
