Abstract
First-principles calculations are presented for fundamental vibrational splitting energies of tritium-bearing molecular hydrogen species with the improved treatment of the nonrelativistic, relativistic, and quantum electrodynamic energy contributions resulting in a total uncertainty of 0.00011 cm^{−1} for DT, or about a 100-times improvement over previous results. Precision coherent Raman spectroscopic measurements of Q(J=0–5) transitions in DT were performed at an accuracy of
