In this paper we simulate the phenomenon “field-induced charge generation” observed in polymers by means of molecular dynamics, and present the time-dependent evolution of bond structure and charge distribution of the polymer chain. The relaxation time of the transformation of one exciton into a couple of polarons is also determined.
