Photoprocesses in Polymethine Dyes Cyanines and Spiropyrane-Derived Merocyanines... [Pg.714]

Polymethine dyes, unless they are stericaUy hindered, are generally present in their all-fra s form. "" The primary photoprocesses in nonaqueous fluid solution are fluorescence and rotation about a polymethine C-C bond prior to population of a ds-photoisomer. [Pg.715]
