Vibronic Interactions

Without actually evaluating the integrals involved, an experimental technique and a mode of analysis have been developed to quantitatively verify van Vleck’s theory of vibronic interactions. The success of the analysis suggests that errors introduced by the computational approximations far outweight those introduced by the partial breakdown of the assumptions upon which the theory is constructed. Specifically, the vibronic transition at 21 200 cm-1 of Co(NH3)63+ has been used to discuss the techniques developed. Furthermore, it has been established that at all temperatures from 293 °K down to 83 °K the ν̃6 vibrational mode of the MX6 entity is primarily responsible (60%) for the admixture of odd parity in the ground and the first excited states of Co (NH3) 63+.

Potential energy curves for the two lowest electronic states X2A″ and A2A′(2Π in linear geometry) of HNF are calculated employing configuration interaction. A vibrational analysis of the A2A′—X2A″ transition is undertaken; stretching and bending modes are treated separately but vibronic coupling and large-angle bending is taken into consideration explicitly. The various vibronic levels including their K-type structure are compared with measured data wherever available and the results indicate that the prediction of vibronic spectra in small molecules on the basis of purely abinitio data is now within reach.
