The expression is related to the Longuet-Higgins¡¯ definition of solute-solvent interaction and fitted into linear regression mode for the determination of transition polarizabilities of 9H-xanthene, 9H-xathone and 9H-xanthione. The result conforms to those earlier obtained when all possible interaction modes are considered. %K Quantum-Mechanical %K Hamiltonian Operator %K Solute-Solvent Interaction %K Linear Regression Mode %K Transition Polarizabilities %U http://article.sapub.org/10.5923.j.pc.20120201.04.html
