The degenerate four-wave-mixing method (DFWM) is used to study the third order susceptibility c (3) and to determine the second order hyperpolarizability <g > of indene and benzofuran molecules. The results are compared to those of carbon disulfide, which is a reference material for DFWM experiments, and to those of benzene and nitrobenzene.

Keywords: Indene; Benzofuran ; DFWM method ; Susceptibility c (3); Hyperpolarizability ; Nonlinear optics.
