✦ Synopsis

Two-photon-resonance four-wave mixing (TPR-FWM) spectroscopy was examined for the study of the permanent electric dipole moments of molecular states. A TPR-FWM process of the type in a three-state x 4 = x 1 Ô x 2 + x 3 dipolar system was considered. The extraction of data for the di †erence in permanent dipole moments (Dl) of states involved in TPR was analysed in the case of resonance TPR-FWM. Resonance TPR-FWM measurements were performed in a solution of the polydiacetylene poly-4BCMU.
