Dm. Bishop et al., A SIMPLE METHOD FOR DETERMINING APPROXIMATE STATIC AND DYNAMIC VIBRATIONAL HYPERPOLARIZABILITIES, The Journal of chemical physics, 103(10), 1995, pp. 4157-4159
A simple method is presented for calculating approximate static and dy
namic vibrational hyperpolarizabilities. It involves determining elect
rical properties in the presence of a static field with and without ge
ometry optimization. This method is readily applicable to all tenser c
omponents of a general polyatomic molecule. (C) 1995 American Institut
