Paper Abstract

We have studied the solvent effects on the molecular first hyperpolarizabilities of the R-4-(N-methyl-pyridinio)- stilbazolium iodide dyes determined by solvatochromism and those of p-nitroaniline and 1-anilinonaphthalene-8-sulfonic acid determined by using HRS techniques, and observed that they are in a linear correlation with the modified reaction field function, a[L((epsilon) )r-bL(n2)] + gETN, with high correlation coefficient ((gamma) >=0.950) in nonselected solvents, in which all of the points are divided into two groups and can be fitted to form two lines which intersect at one point for each compound. From the ordinate of the intersection, the intrinsic molecular first hyperpolarizabilities for each compound in pure solid state can be estimated, according to the hypothesis of the equal energy levels of the polarized surrounding molecules (solute or solvent) to influence on the solute molecule both in solid state and in some solution systems. Therefore we developed a simple experimental method for determining the intrinsic first hyperpolarizabilities of the stilbazolium- like dyes, which excludes the solvent effects.
