The effect of α-hydroxyacetamide upon the formation of an alkoxy radical in α-chloroacetamide single crystals: An ESR study

Abstract

The inclusion of 0.05 to 20 mol% of α-hydroxyacetamide in single crystals of α-chloroacetamide has shown that the four line ESR pattern observed for x-ray irradiated α-chloroacetamide single crystals at 77 K is due to the alkoxy radical ⋅OCH2CONH2. The intensity of the four line ESR pattern is proportional to the concentration of α-hydroxyacetamide up to 1 mol% at which point it levels off and then decreases above 5 mol%. The alkoxy radical is not observed in pure α-hydroxyacetamide crystals.
