✦ Synopsis

Quantumshemical calculations have been performed for rotations around the different CC bonds of streptocyanine eations and of various ion pairs of TMC+ and PM? with Cl-as the gegenion (counterion) in order to explain the experimentally well known temperature dependence of the activation energy for the thermal isomerization.

A friction model for cis-trans isomerization is proposed. The friction is a linear combination of two limits, reflecting relative time scales of system and solvent motiohs. The resulting extended Kramers equation fits MD results exactly and is applicable to real isomerizing systems as well.

The thermal cis-trans isomerization of an amphiphilic azo compound in the assembled monolayer film has been investigated kinetically, using an electrochemical approach to follow the reaction process. The isomerlzation in the rigid monolayer film was found still to follow the first-order kinetics. Su

The light induced isomerization of thioindigo (I) and 6,6'-diethoxy-thioindigo (II) has been investigated by means Of nanosecond flash photolysis and steady state methods. A mechanism is proposed in which a common triplet state generated from both the trans and cis isomers is responsible for the iso
