The title compound 1,3,3,5,2'-pentamethylspirooxazine (I) is synthesized and identified by IR, 1 H NMR and elemental analysis. The time-resolved transient absorption spectra of I are investigated by nanosecond laser flash photolysis. The photolysis of I in solution excited by 248 nm laser pulse results in two different colored species. One of them is a short-lived species (CT intermediate),...
