Notes

1DeltaG(3/2) = 1816.7 Takezawa and Tanaka, 1972, DeltaG(5/2) = 1723.7 Takezawa and Tanaka, 1972; from Rydberg series of HD Takezawa and Tanaka, 1972. Ab initio calculations Bishop, 1976 give DeltaG(1/2) = 1913.005 Bishop, 1976.
2All bound rotational and vibrational levels derived from the ab initio potential function in the adiabatic approximation are listed by Hunter, Yau, et al., 1974; see also Bishop and Wetmore, 1973. The rotational constants in the table are based on these calculated levels Hunter, Yau, et al., 1974 using v=0 and 1 only.
3Rotation-vibration sp.5
4From D00(HD), I.P.(HD), and I.P.(H). A second dissociation limit corresponding to H + D+ is only 0.00370 eV higher. The theoretical value for D00(HD+)= 2.667679 eV Bishop, 1974, Bishop, 1976.
5Several lines of the 1-0, 2-1, 3-2 infrared bands have been observed and measured with high accuracy by Wing, Ruff, et al., 1976 but there are not enough lines to obtain "observed" values for the rotational constants. The lines show a splitting of 0.0010 cm-1 corresponding to the difference in spin splitting in the upper and lower state.
