INVESTIGATION OF THE (1)E(2G)(-) STATES IN CYCLIC POLYENES

摘要

An analysis withing the one-dimensional Hubbard model of the (1)E(2g)(-) type state in cyclic polyenes is reported. In terms of the resonance integral beta, a small beta analysis and asymptotic large beta analysis have been carried out. Energy as a function of beta has been calculated numerically, and a second state with (1)E(2g)(-) symmetry has been found. Some missing information about the higher momentum state of this symmetry is provided. (C) 1995 John Wiley & Sons, Inc. [References: 15]
