Recently the solvent effect on the [4+2] cycloaddition of singlet oxygen to cyclic dienes has been subjected to a multiparameter analysis. A pre-equilibrium with charge-transfer character is involved, which is affected by the solvent through dipolarity-polarisability (n ) and solvophobic interactions ( Sjf and Another multiparameter analysis has been published by Gajewski, demonstrating the... 

Very recently, Isobe et al.4,5 have shown that the charge-transfer (CT) configuration in Fig. 2C play an important role of the intersystem crossing from triplet (T) molecular oxygen (302) to the singlet one via the spin-orbit (SO) interaction in the course of dioxetane (DO) (dioxetanone (DON)) formation reactions.
