transitions, with term energies of 0.3982 (7) and 0.7422 (10) eV, respectively, determined by the shift in peak location from A1. These reported term energies are more precise than those previously reported (0.40(2) and 0.77(3) eV, respectively), and are in good agreement with our computed term energies of 0.56 and 0.88 eV, validating this reassignment.
