Spin-Coupled Generalized Valence Bond Theory: New Perspect<b>i</b>ves on the Electronic Structure of Molecules and Chemical Bonds

Spin-Coupled Generalized Valence Bond (SCGVB) theory provides the foundation for a comprehensive of electronic structure molecules. SCGVB offers compelling orbital description molecules as well an efficient and effective zero-order wave function calculations striving quantitative predictions molecular structures, energetics, other properties. The orbitals in are usually semilocalized, most molecules, they can be interpreted using concepts familiar to all chemists (hybrid orbitals, localized bond pairs, lone etc.). also new perspectives on nature bonds such C2, Be2 SF4/SF6. contributes unparalleled insights into underlying cause first-row anomaly inorganic chemistry organic mechanisms reactions. accounts nondynamical correlation effects and, thus, corrects serious deficiency (RHF) functions. Dynamical effects, which critical predictions, taken account multireference configuration interaction or coupled cluster calculations.
