Orbitals bonds and antibonding

Bonds interact with one another in molecules. The bond interactions are accompanied by the delocahzation of electrons from bond to bond and the polarization of bonds. In this section, bond orbitals (bonding and antibonding orbitals of bonds) including non-bonding orbitals for lone pairs are shown to interact in a cychc manner even in non-cychc conjugation. Conditions are derived for effective cychc orbital interactions or for a continuous orbital phase.

A masterpiece written by a Nobel Prize winner, one of the founders of solid-state quantum chemistry. Solid-state theory was traditionally the domain of physicists. Some concepts typical of chemistry, such as atomic orbitals, bonding and antibonding effects, chemical bonds, and localization of orbitals, were usually absent in such descriptions. They are highlighted in this book.
