Dioxetans diagram

Figure 14.11. (a) Orbital and (b) state correlation diagrams for the decomposition of dioxetane. The observed chemiluminescence may be due to intersystem crossing (ISC) to the triplet manifold in the region denoted by the shaded circle in (b).

These results have been rationalized by means of the correlation diagram shown in Figure 7.57 (Turro and Devaquet, 1975). The ground state of tetra-methyl-l,2-dioxetane correlates with a doubly excited state of the...
