Figure 2. Partitioning of energy to 1 provided by differing mechanistic origins.

Figure 2

a, The thermal free-radical chain formation of 1 from 7 provides relatively little Evib. b, The photochemical cleavage of the triplet state of 5 provides more energy to 1. c, The direct cleavage of singlet excited 7 affords 1 with a large wavelength-dependent energy.
