Gg. Lazarev et al., THE ROLE OF DOPANT GEOMETRY IN THE PHOTOINDUCED FORMATION OF RADICAL PAIRS IN CRYSTALS OF 2,6-DI-TERT-BUTYL-4-METHYLPHENOL AND 2,6-DI-TERT-BUTYLPHENOL, Chemical physics letters, 212(3-4), 1993, pp. 319-325
Radical pairs are formed by photolysis of single crystals of 2,6-di-te
rt-butyl-4-methylphenol (ionol) (1) or 2,6-di-tert-butylphenol (2), do
ped by several different molecules, and investigated by the EPR method
. A possible two-hydrogen-atom transfer is discussed as the photochemi
cal act.
