Abstract
Spiropyrans are known to exhibit photochromism in solution, however, the configurations of transient species, photomerocyanines, produced in the photochromic reaction have not been well understood. In this paper, the configurations of the photomerocyanines of 1′, 3′, 3′,-trimethylspiro[2H-1-benzopyran-2, 2′-indoline] (BIPS) and 2,2′-spirobi[2H-1-benzopyran] (SBP) have been investigated by time-resolved resonance Raman spectroscopy with the aid of complexation with metal ions.
