Abstract
Radiation-induced organic radicals in CaCO3 doped with gamma-aminobuty ric acid and glycine, and Li2CO3 with adsorbed glycine were investigat ed by electron spin resonance. Isopropyl radicals occurred in CaCO3 do ped with gamma-aminobutyric acid. A signal at g = 2.0046 exhibiting in teraction with a proton, a nitrogen and another proton was detected in glycine-doped CaCO3. The signal shows strong anisotropy of interactio n with the first proton. The signal was also found in Li2CO3 with adso rbed glycine. The result revealed that amino acid molecules are on the surface of CaCO3. Copyright (C) 1996 Elsevier Science Ltd
