    Notes: The all-valence INDO method has been modified for the inclusion of spin-orbit coupling effects. In the method presented, the Hamiltonian includes spin-orbit coupling and the basis set constitutes the singlet and triplet determinental wave functions constructed from molecular orbitals resulting from nonrelativistic calculations. Eigenvectors obtained are later used for the evaluation of transition probabilities among different states. The results presented include lifetimes of different states of organic molecules and transition energies for halogen molecules and they are in a good agreement with experimental results. © 1992 John Wiley & Sons, Inc.

    Notes: The potential energy curves for the intermolecular proton transfer in complementary base pairs and respective hydrogen bonded model systems have been studied at the semiempirical all-valence and ab initio STO-3G level. The proton transfer probability was found to be markedly greater in excited electronic states than that of the ground state. Substantial lowering of the potential barrier height for the coupled double proton transfer in model (HCOOH)2 system has been observed when the dynamics of zero-point vibrational deformations of the heavy atom skeleton and the environmental effects were taken into account in nonempirical STO-3G calculations. The results of quantum-chemical calculations indicate on the possibility of the double proton transfer in complementary base pairs corroborating the submolecular Löwdin hypothesis on the mechanism of spontaneous mutations.
