The nuclear magnetic resonance of 31P in antiferromagnetic Mn2P2O7 has been investigated at constant r.f. frequencies with the external field smaller than the spin-flop field. Resonance measurements were made in a single crystal sample at liquid helium temperatures. Experimental data, including the angular dependence, the external field dependence, and the temperature dependence of the resonances, are satisfactorily explained by the spin Hamiltonian formalism for NMR in antiferromagnets, proposed by the authors. NMR results confirm the spin direction obtained from susceptibility measurements, and establish the magnetic space group as C2c2.
