Paper Abstract

Stepwise reversible rearrangement of dicarbocyanines upon excitation of instable primary photoisomers is studied using nanosecond pump-probe laser spectroscopy. The structure of secondary photoisomers, the probabilities and activation energies of the second photoisomerization stage are found. The mechanism of recovering stable molecules upon relaxation of secondary photoisomers is determined.
