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.

2,6-Di-tert.-butyl-4-methylphenol (2,6B4M), is one of a number of phenolic antioxidants, which are approved for service use in aviation turbine fuel (AVTUR). The specified level for total active material in hydrogen-treated fuel is between 17 and 24 mg/l, and for non-hydrogen-treated fuel the level
