Line shape and spin lattice relaxation time of proton magnetic resonance of copper acetate monohydrate are studied at temperatures from 77°K to 300°K. The orientation and length of the line joining two protons in water molecules can be determined from the variation of line splitting with field direction at liquid nitrogen temperature. The result is found to be consistent with the positions ascribed to hydrogen nuclei on the hydrogen bonds expected from the crystal structure. The angular variation of line shape is explained by considering the rotation of methyl groups and dipolar interaction between protons. The temperature dependence of line shape and spin lattice relaxation time is discussed based on the theory fluctuating local magnetic field due to triplet Cu++ ions.
