Bond overlap population
WebAn example of quantum mechanical schemes is the oldest and most widely used Mulliken population analysis [1], which simply divides the part of the electron density localized between two atoms, the overlap population that identifies a bond, equally between the two atoms of a bond. Alternatively, empirical methods to allocate atomic charges to ... WebMar 3, 2014 · The electron-transfer path is investigated using the bond overlap population (BOP) analysis [20] between C atoms.

Webvery similar to that between bond length and bond number described by Pauling (1960) for C-C bonds. A corresponding empirical relationship for S-O bonds has been derived by Gillespie and Robinson (1963), indicating that bond overlap population is directly related to bond order. However, the dependence of the
