Photobleaching and absorption recovery of the fundamental state of pinacyanol have been investigated in different solvents. using a single picosecond puke. In a viscous solvent, glycerol, the recovery time constant is T = (330 c 30) ps which may be compared with the fIuorescence lifetime r = (302 f

In addition to the yellow emission ascribed to the 3 aggregates of l,l'-diethyl-2,2'-cyanine, this compound also exhibits a high-energy emission around 400 nm in dilute aqueous solutions (c<~D-~ mol 1-l). It was found using time-resolved emission measurements that protonation of l,l'-diethyl-2,2'-cy
