| Popis: | The results of measurements of the proton spin–lattice relaxation time T1 in ice are reported. The ice samples were single crystals grown by zone refining at atmospheric pressure. The measured activation energy for the T1 process is 14.1 ± 0.1 kcal/mole. No anisotropy of T1 is observed. A theoretical calculation of T1 is presented, from which molecular displacement times are deduced. |
