In this work the classical valence-bond VB theory of the 1930s is recast Ε½ . in a fully ab initio modern form. The basic premises are simply i that valency is associated with singly occupied orbitals on the constituent atoms of a molecule, more Ε½ . tightly bound electrons being assigned to a ''core,
## Abstract Thermal motion of CH is investigated by performing an __ab initio__ molecular dynamics method with the secondβorder MΓΈllerβPlesset (MP2)/6β311G\*\* force field. In the trajectories obtained at 400 K, we have observed rapid interconversion behavior of the geometrical parameters of CH wit
The third-order ab initio effective valence shell hamiltonran of quasi-degenerate many-body perturbation theory is calculated for the vaience state potential curves of CH and CH" simultaneously. The results are in accord with experiment and configuration interaction calculations, and they have appli
The 22 possible valence isomers of the (CH), and (SiH), systems have been studied by ab initio molecular orbital calculations at the MP2/6-31G\*//6-31G\* + ZPE level. Optimized geometries, relative energies, and, for some selected compounds, vibrational frequencies are reported. The systematic diffe
