Notes

D₁ = 4.9E-4.

Preliminary data only.

Band origins in the tables for PtH and PtD correspond to the energy of J'=0 relative to J"=0. Vibrational constants recalculated accordingly.

From the corresponding value for PtD.

Perturbations in both v=0 and v=1.

Predissociation above v=0, J=12.5, see Kaving and Scullman, 1971.

D₁ = 3.94E-4.

Perturbation in v=1 at J~6.5, see Scullman, 1971.

D₁ = 3.5E-4.

(v=0, ..., 3).

Ω-type doubling; for details see Scullman, 1965, Kaving and Scullman, 1971, Kaving and Scullman, 1974.

B₁= 5.244, B₂= 4.924, B₃= 4.517 (v=3 perturbed for J ≥ 10.5).

D₁(E-4 cm^-1)= 3.68, D₂(E-4 cm^-1)= 4.42, D₃(E-4 cm^-1)= 8.8.

Ω-type doubling; see Kaving and Scullman, 1971.

D₁ = 6.08E-4.

x₂ ~1320; see Kaving and Scullman, 1971.

D₁ = 2.84E-4

Not certain that this is the ground state.

D₁ = 2.60₇E-4.

From the predissociation in v=0 of B (²Δ)_5/2, assuming that X₁ is the ground state.
