Abstract
The possibility to use a partitioning of the first‐order density matrix to obtain a quantum mechanical basis for bond energy schemes is pointed out. Methods for obtaining such partitionings are discussed. The problems arising, when a bond energy scheme is based on the kinetic energy of the electrons is discussed in the light of the quantum mechanical virial theorem. A small numerical example is given.Keywords
