Abstract
In this paper we present ab initio calculations for the evaluation of molec ular hyperpolarizabilities of symmetric cyanine molecules. The influence on the electronic properties of the presence of a counterion is discussed tak ing into account the relative position of the molecule and the counterion i tself. Use is made of the vibrational method to determine the vibrational c ontribution to molecular hyperpolarizabilities. (C) 2001 Elsevier Science B .V. All rights reserved.
