An NMR pulse spectrometer has been used to determine the triton and proton free precession frequencies for HT molecules in a gas to within +- 2.7 x 10/sup -9/ and the spin-spin interaction energy (J/sub p/T=299.3 +- 0.2 Hz). A calculation is given of the difference between the screening of the triton and the proton in HT. The calculation is based on the Fraga-Ransil ground-state wave function, and the correction antisymmetric functions are obtained by a variational method subject to the condition that the electric dipole moment of HD should be accurately described. Corrections due to mutual nuclear screening are also taken into account. Calculations have shown that the triton in HT is screened more effectively than the proton by a factor of 20.4 x 10/sup -9/. The corresponding factor for the deuteron in HD is 15.0 x 10/sup -9/. The final result for the magnetic moment of the triton is 1.066 639 908 +- 3 and the magnetic moment of the deuteron is 0.3070121983 +- 8 in units of the proton magnetic moment.
