Tetramethyl-1,2-dioxetane chemical titration

Tetramethylammonium ozonide, 736 Tetramethyl-l,2-dioxetane (TMD) chemical titration, 1224 chemiluminescence, 1221, 1234 quantum yield standard, 1224, 1226 N,N, N, A -Tetramethyl-p-phenylenediamine hydrogen peroxide determination, 735, 631, 633... 

The specificity of this reaction has been used to chemically titrate both the excited-singlet acetone and the triplet acetone produced through thermal decomposition of tetramethyl-I,2-dioxetane. (Cf. Section 7.6.4.) For this purpose the thermolysis was carried out in the presence of /ra/ii-l,2-dicy-anoethylene, and the quantities of singlet and triplet acetone formed were obtained from the yields of dioxetane and c/s-I,2-dicyanoethylene, respectively (Turro and Lechtken, 1972).
