摘要
An extended Longuet-Higgins formalism recently utilized to obtain generalized Born-Oppenheimer equations including the geometrical phase effect has been used to study a three-fold pseudo-Jahn-Teller type electronic degeneracy. The results of dynamics calculations carried out with the novel formalism are compared with Born-Oppenheimer (geometrical phase ignored), extended Born-Oppenheimer, and coupled three-state ones for the same system. The theory shows unprecedented simplicity while depicting all features.
