Abstract
Absolute net nuclear polarizations and reaction yields are determined for the products of geminate radical pairs formed after triplet α-cleavage of di-tert-butyl ketone and during the singlet photo-Fries reaction of p-methylphenyl- p-chlorobenzoate. These and other experimental data are compared with values predicted by several variants of the high-field radical pair theory. Full agreement between experiment and theory is found to require proper inclusion of electron exchange effects in the latter, and a previous analytical model is modified to allow for this.
