We have investigated the ultrafast dynamics of trans-1,3,5-hexatriene in cyclohexane and acetonitrile solutions following photoexcitation to the 1 1B u state. The transient absorption in the visible region consists of an instantaneous rise (< 150 fs) and decay in less than 500 fs, whose time constan
