Why “Effective” Bonds exist when “Real” Bonds are Absent: The Electronic Structure of the (1.1.1.) Ps SCP-MO computations by Newton and Schulman., has no bond linking the bridgehead carbons, but, nonetheless, it is comparatively very stable.. I now show that MOVB theory. easily accounts for these “strange” observations by comparing the electronic structures of the following three molecules.

Structural Isomerism and the Electronic Basis for Ligand Segregation on C2 CoresOne of the most fascinating trends of molecular stereochemistry is the tendency of ligands to segregate into sets when attached on carbon cores. A typical example is provided by the comparison of 1,1 and cis 1,2-difluoroethylene, henceforth referred to as G and C 1,2 difluoroethylene, respectively.

Frontier Configuration Theory of Spin SelectionThe spin selection problem revolves about the determination of the sign and magnitude of the energy difference between two different spin states . for a given geometry, g, and a given number of electron pairs, n. For our purposes, g can be either a Hückel AO (HAO) or Möbius AO (MAO) geometry.
