Resonance Raman spectra of transient species of 1 ',3',3'-trimethylspiro-[2H-l-benzopyran-2,2'-indoline] in various solvents reveal that at least four transients having merocyanine-like structures are involved in the photochromism of this compound. It is concluded that the transient species in aliph
