The electron spin resonance of I-irradiated single crystals of carbohydrazide has been investigated at liquid nitrogen temperature. The free radicals irradiated at dry ice temperature are identified as the singlet state NH2-NH-CO-NH-NH. The isotropic and anisotropic hyperfine components of α-nitrogen are found to be aN=16 Gauss and bN=13 Gauss respectively. The spin densities of the hydrogen s-orbital and the nitrogen sp-orbitals are ρn1s=0.043, ρn2s=0.29 and ρn2p=0.76 respectively in accordance with the McConnell calculation.
