Glycine methyl ester (5mg) in 7.5 M LiCl after 45 minutes of gamma irradiation at 77K. A. Sample at 77K after electron addition which results in both deamination by C-N bond cleavage to form •CH2CO2CH3 and C-O bond cleavage to form the methyl radical (CH3•) which gives rise to the sharp 1:3:3:1 spectrum with 23 G separations. The background signal of the Cl2−• has been subtracted. B. After annealing to 155K for 10 minutes which results in the loss of almost all the methyl radical signal and leaves the •CH2CO2CH3. This spectrum was recorded at 77K after annealing. The three markers are separated by 13.09 G each. The middle marker is at g=2.0056.
