Abstract
FT-IR and resonance Raman spectra of the transient species of 2,3-diphenylindenone oxide generated by irradiation with UV light have indicated that the reversible photo-coloration reaction of this compound is well interpreted in terms of valence tautomerization involving transient species having a benzopyrylium elate structure. Frequency shifts and intensity changes in both the IR and Raman spectra of the transient species in different solvents suggest, however, that at least two transients are involved in the photo-coloration.
