ESR study of the carbon 13 hyperfine coupling tensors of the (COOH)H(OH) and COOH(OH 2) radicals

(COOH)(H)OH and (COOH)(OH) 2 radicals trapped in single crystals of glycolic and mesoxalic acids are studied by EPR. 13C and hydrogen coupling hyperfine tensors are determined. It is concluded from results relative to 13C couplings that both radicals are planar.
