Abstract
The potential functions of inversion in the S-1 states are determined from the inversion transitions (out-of-plane C=O vibrations) found in the S-1<--S-0 vibronic spectra of acetyl halide molecules. The high in tensities of the hot inversion transitions are explained by the high p robabilities of these transitions. The literature values of the invers ion potentials (equilibrium values of angles formed by the C=O bonds d eviating from the planes) of formyl halide molecules in the S-1 states are refined. The inversion potentials of formyl and acetyl halides ar e similar.
