Paper Abstract

The longitudinal component of the static first hyperpolarizability per unit cell of model finite and infinite polymethineimine chains has been computed at the uncoupled Hartree-Fock level of approximation. Particular attention has been paid to the correspondence between the results associated with the large oligomers and the direct polymeric results. We have investigated as a function of increasingly large chain length the effects of the heteroatomicity and the bond alternation upon the electron density alternation and centro-symmetry which modulate the amplitude of the longitudinal first hyperpolarizability per unit cell.
