摘要
The potential energy surfaces of the H2CO, F2CO, and Cl2CO molecules in the lower excited singlet and triplet electronic states were studied by multiconfigurational quantum chemistry methods. The dependence of estimates of the potential barrier to inversion on the method for calculations is discussed. The theoretical and experimental estimates of inversion vibrational levels are compared.
