Using degenerated four wave mixing techniques and optical Kerr effect we studied the optical non-linearities of excited t-stilbene solution. Strong enhancement of the non-linear signal between the excited and ground states is observed and related to the third order non-linear susceptibility ( xc3))
New details of the dynamics and spectroscopy of trans-stilbene are revealed by picosecond excitation of jet-cooled and collision-free molecules. The fluorescence spectra clearly show the low-frequency torsional modes of the ground state. The time-resolved fluorescence following $1 excitation exhibit
