Abstract
Tunable third-harmonic generation and nondegenerate four-wave mixing experiments were performed on polythiophene thin films to produce six independent nonlinear-optical spectra. An essential states model consisting of three electronic excited states has been compared with the spectra. Inclusion of a Raman state could improve the fit to two of the spectra.
