摘要：

We report on the NMR free induction decays (FID) fr om solid tritium (T-2), deuterium-trititum (D-T), and H-2 HD and D-2 containing 2% tritium. The FID in pure components is typically a beat decay for spin concentrations >30%, can exponential for spin concentrations <10%, and a Gaussian or Gaussian-exponential for spin concentrations in between. In mixtures of DT or HD, the deuteron FID is a Gaussian-exponential while the T or H FID is typically a beat decay ol Gaussian depending on temperature. The linewidth is shown to consist mostly of inter molecular and intramolecular contr ibutions, with a small component resulting from unpaired hydrogen atoms created by the tritium radioactivity.
