Correlation analysis of chemical bonds (CACB) II: Quantum mechanical operators for classical chemical concepts
The workers apply correlation analysis of chemical bonds (CACB) to simple organic reaction paths. CACB, an operator-based formalism for analyzing the electronic structure for molecule, clarifies how bond exchange processes relate to changes in covalent bond orders and bond interaction coefficients. For single bond-exchange processes, the bonds correlation typically is negative for interchanging bonds. For two bond-exchange processes, this coefficient can be either negative or slightly positive near zero, reflecting the nature of the bond exchange process. The simplest formalism can, sometimes, lead to unphysical values for the atomic valence and the bonds correlation coefficient. The origin of this behavior was analyzed and attributed to the non-Hermitian property of the operator. The authors show how to avoid this problem by symmetrizing the operator through use of orthogonal atomic orbitals.
