Radical pairs are formed by photolysis of single crystals of 2,6-di-tert-butyl-4-methylphenol (ionol) (1) or 2,6-di-tert-butylphenol (2 ), doped by several different molecules, and investigated by the EPR method. A possible two-hydrogen-atom transfer is discussed as the photochemical act.

Intermediate radical products, which are formed when monocrystals of sterically hindered phenols containing lo-' M Z&k&tbutyl quinone diazide are photolysed, have been studied employing EPR. We have identified the formation of carbenes and several types of radical pairs It is found that, with a rise
