摘要

The dynamics of C-O bond cleavage followed by structural change to merocyanine in the photochromic reaction of a spirooxazine derivative was studied by femtosecond transient absorption spectroscopy. The very broad spectra following the Sn-S1 absorption spectrum of spirooxazine were observed within 2 ps after excitation, and assigned to the absorption from the transition state. The rate constants of C-O bond cleavage and the relaxation from the transition state to a metastable merocyanine were estimated to be approximately (700 fs)-1 and (470 fs)-1, respectively.
