Abstract
The methanol molecule is used as a test case for studying the simultaneous action of solvation and vibrational effects on static and dynamic hyperpolarizabilities within the reaction field model. The calculations indicate that the medium can play a significant role for the vibrational correction. The calculated third-order optical nonlinear susceptibilities of methanol in gas and liquid phases are in fair to good agreement with their experimental counterparts.
