Temperature dependence of 17 O nuclear quadrupole resonance frequencies was measured in solid 2-nitrobenzoic acid by a 1 H-17 O nuclear quadrupole double resonance technique. The experimental results show the presence of a fast exchange of hydrogen atoms between two nonequivalent positions within th
