An ESR Study of Hydrogen-Bombarded 9-Methyladenine

The damage in 9-methyladenine resulting from discharge-generated hydrogen atoms is compared with the damage from ionizing radiation. It is concluded that: (1) hydrogen abstraction from the methyl occurs as a result of X irradiation but not H bombardment, (2) hydrogen addition occurs at C8 but not C2...

Zusammenfassung:	The damage in 9-methyladenine resulting from discharge-generated hydrogen atoms is compared with the damage from ionizing radiation. It is concluded that: (1) hydrogen abstraction from the methyl occurs as a result of X irradiation but not H bombardment, (2) hydrogen addition occurs at C8 but not C2 as a result of H bombardment, and (3) the radical characterized by an ESR singlet, formed by X irradiation and H bombardment, is due to hydrogen addition to the C4-C5 aromatic bond.
