Chemiluminescence of Dimethyldioxetanone

Dimethyldioxetanone undergoes two distinct thermal reactions which generate electronically excited states. The unimolecular decomposition at 30.0(DEGREES)C produces excited singlet and triplet acetone, with efficiencies of 0.1 and 1.5% respectively. The composite activation energy for formation of singlet acetone is 3-4 kcal/mol greater than the activation energy for the thermal disappearance of dimethyldioxetanone. This result is interpreted in terms of two parallel competitive pathways for dioxetanone decomposition, the more highly activated one of which leads to excited acetone.
