Observable Parameter

A computational method was devised to explore the relationship of charge separation, geometry, molecular dipole moment (mu), polarizability (alpha), and hyperpolariz-abilities (beta, gamma) in conjugated organic molecules. We show that bond-length alternation (the average difference in length between single and double bonds in the molecule) is a key structurally observable parameter that can be correlated with hyperpolarizabilities and is thus relevant to the optimization of molecules and materials. By using this method, the relationship of bond-length alternation, mu, alpha, beta, and gamma for linear conjugated molecules is illustrated, and those molecules with maximized alpha, beta, and gamma are described.

Abstract Molecular The classification of the types of excited molecular structures suggested in a preceding paper1, can be used for interpretation and prediction of fluorescence ability of large classes of conjugated organic molecules. Possible electronic conditions for S2- and dual fluorescence are discussed. An extension of Kasha's rule is suggested.
