The reaction of O2(a,1Δg) with N,N-dimethylisobutenylamine has been studied in the gas phase at 298 K, a total pressure of 4 Torr, and an oxygen partial pressure of 0.007-4.0 Torr.The reaction forms a chemically activated dioxetane that decomposes with chemiluminescence (CL).CL spectra were obtained, and deconvolution showed them to consist of acetone T1 -> S0 and S1 -> S0 and no other molecular emissions.The T1 state was efficiently quenched by O2.The integrated intensity ratio, I(T1)/I(S1), was 1.3 at P(O2) = 0.The T1 -> S0 spectrum shows its onset at 366 nm and peak intensity at 440 nm.
