Research Abstract

An Iterative transfer perturbation method was proposed and formulated at the levels of the extended Huckel method and of the abinitio SCF method. The program-mings of this method were carried out and then this method was applied to aperiodic system of polymers. At the level of the extended Huckel method, this method was applied to aperiodic polyacetylene systems. First example is polyacetylene in which a carbon atom was replaced by nitrogen cation, second one is polyacetylene inter-acting with Li atom, and final one is polyacetylene system with interchain-interaction. For all these systems, our perturbation method was found to give excellent results and proved to be very useful. At the level of the abinitio SCF method, this perturbation was applied to the hypothetical polymer system consisting of many hydrogen molecules arranging in one dimension. The result was also found to be excellent although there was difficulty in convergence for some cases.
