Notes

1D1 = 4.9E-4.
2Preliminary data only.
3Band origins in the tables for PtH and PtD correspond to the energy of J'=0 relative to J"=0. Vibrational constants recalculated accordingly.
4From the corresponding value for PtD.
5Perturbations in both v=0 and v=1.
6Predissociation above v=0, J=12.5, see Kaving and Scullman, 1971.
7D1 = 3.94E-4.
8Perturbation in v=1 at J~6.5, see Scullman, 1971.
9D1 = 3.5E-4.
