Nuclear coupling of 33S and the nature of free radicals in irradiated crystals of cystine dihydrochloride
Description
The 33 S hyperfine structure has been observed and analyzed in the electron spin resonance of γ-irradiated single crystals of cystine dihydrochloride at 77°K and at room temperature. The radicals observed at room temperature and previously assigned as RCH 2 S are proved to be disulfide radicals, RCH 2 SS. However, the RCH 2 S radical is identified by the 33 S measurements in samples irradiated at 77°K, annealed at 200°K, and observed at 77°K. This monosulfide radical appears to undergo reactions to form disulfide radicals at room temperature.
