Orientational relaxation of rhodamine 6G in a series of normal alcohols, ethylene glycol, chloroform and formamkie has been studied using picosecond light pulses. The effecis of hydrogen bonding and the structure of the liquids on the molecular rotational motion are examined. To examine the effects

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))
