Abstract

Multiresonant four wave mixing provides information about each resonant level. Multiple resonances also provide sensitivity and selectivity. Specific methods for obtaining unambiguous information from two input frequency and three input frequency nonlinear experiments have been developed. Experimental data have been obtained for the single site pentacene in benzoic acid system, and for the four site pentacene in p-terphenyl system.
