The biradicals generated in the Norrish type II reaction from the triplet manifold have been observed using laser flash photolysis techniques. The spectra and extinction coefficients closely resemble those of typical ketyl radicals. Typical lifetimes are in the 40 to 100 ns range depending on the solvent. Their interaction with oxygen is essentially diffusion controlled.
