Computer simulation of liquid anisotropy. V. Nonlinear molecular dynamics at high field strengths

Abstract

The computer simulation method has been used to investigate the molecular dynamics of C2v symmetry asymmetric tops at points along the Langevin function to saturation. The first order linear/angular velocity correlation function is visible in a moving frame of reference and becomes increasingly oscillatory at high field strengths. A single molecule rototranslational Langevin equation cannot explain these results without involving nonlinear interactions between the molecule and it surroundings. The computer simulation has been used to predict the results of experiments on laser-induced birefringence.
