Selective excitation in harmonic molecular systems by optimally designed fields

Abstract

The goal of selective local excitation in a harmonic system can be achieved via optimally designed field. For achieving a given primary objective of selective excitation in the molecular system there may be a family of optimal fields that correspond to a variety of additional physical concerns. The optimal fields cooperate with the dynamical behavior of the molecular system and intramolecular energy transfer can be manipulated to help achieve the objective of selective local excitation. Long duration selectivelocal excitation is studied and the effect of the molecular polarizability on the optimal fields is considered. In some cases the presence of polarization will not effect the quality of the finally achieved objective while in other cases its significant presence can make more difficult the achievement of selective local excitation.
