Abstract

Certain cyanines undergo characteristic changes in absorption in going from, for example, methanol as solvent to benzene (or similar non-charge stabilizing solvent, e.g., toluene). Such changes are due to shifts in equilibrium between stereoisomers. An explanation is offered why all-trans isomers preponderate in benzene, and half-turned and/or hemicyanine structures in methanol.
