We separate the electronic and nuclear contributions to the third-order nonlinear optical susceptibilities χ_{ijkl}^{〈3〉} using degenerate four wave mixing. This method allows to know the physical origin of the optical nonlinearities of new soluble tetrathiafulvalene derivatives and deduce the values of the second-order hyperpolarisabilities γ. The values of γ for the studied compounds are about 10^{5} greater than for CS_{2}.
