Abstract

A nonlinear dynamical equation for the electronic collective motion is presented by employing the traditional time‐dependent procedure. The equation is applied to the model π‐electron system of ethylene, and the effects of nonlinear interactions are investigated using its several states as reference states. It is shown that the nonlinear correlation plays an important role in describing the change of the lower excited states.

## Abstract Dynamical screening in π‐electron systems is studied by the equations of motion method. By using a partitioning technique on the equations of motion we can obtain simple expressions for the effect of dynamical screening directly on the transition energies and transition moments in π‐ele
