RAYLEIGH-SCHRODINGER PERTURBATION-THEORY FOR NONLINEAR SCHRODINGER-EQUATIONS WITH LINEAR PERTURBATION

Rayleigh-Schrodinger-type perturbation theory is developed for the nonlinear Schrodinger equation, which contains a linear perturbation operator. Typical applications involve the self-consistent reaction-field model of solvent effects. Consideration of external perturbations, like electric fields, allows. calculation of the response properties of solvated species. The general formulae allow development of a consistent Moller-Plesset perturbation theory of solvated molecules. (C) 1993 John Wiley & Sons, Inc.
