Conformations of the Free Radical in Irradiated α-Aminoisobutyric Acid

Abstract

The electron paramagnetic resonance spectrum of x-irradiated α-aminoisobutyric acid was studied in single crystals irradiated at 77°K and allowed to warm up gradually. Different conformations of the free-radical (CH3)2CCOOH were observed. The g tensor and the hyperfine splitting tensor were determined for each conformation.
