Quasielastic neutron scattering data indicate that the hydrogen-bonded amide protons in the self-organising system 3,5-dimethylpyrazole undergo a short-range hopping motion between two equivalent sites straddling the direct N ... H hydrogen-bond ads. The activation energy for this motion has been measured as being 1.7(1) kJmol(-1). (C) 2000 Elsevier Science B.V. All rights reserved.
