We have measured the third-order susceptibility v h3i ijkl of a C 60 -TTF compounds in tetrahydrofuran (THF) solutions using the degenerate four wave mixing technique at k ΒΌ 532 nm in the picosecond regime. To know the physical nature of the optical non-linearities, we separate the electronic and nu
