Notes
| 1 | Strong perturbations. Constants valid near J=0 only. |
| 2 | From perturbations in c1(v=0). |
| 3 | Estimated energy of v'=0,N'=0 relative to X 1Σ (v=0,N=0). |
| 4 | The only observed level is strongly perturbed by more than one state. Constants refer to unperturbed region around J=l9. Origin of 0-0 band (not observed) at 46692 cm-1. |
| 5 | Perturbations in v=0,1; bands going to v'=0 of AgD have not been analyzed. Constants refer to unperturbed regions near J=0. Large Λ-type doubling. AgH: Δνef(v=0) = 0.244J(J+1)-... AgD: Δνef(v=1) = +0.0772J(J+1). |
| 6 | Constants refer to unperturbed region near J=O. Large Ω-type doubling; AgH: Δνef = 0.156J(J+1)-... AgD: Δνef = 0.0337J(J+1)+ ... |
| 7 | P branch very weak or absent. |
| 8 | Approximate constants for the deperturbed state. Origins of the 0-0 bands at 44225.0 cm-1 (AgH) and 44277.4 cm-1 (AgD). v=1 is free of perturbations. AgH; B1=4.4l2, D1=3.5E-4, ν0(1-0)=45322.8 cm-1; AgD; B1=2.343, D1=0.95E-4, ν0(1-0)=45097.8 cm-1. |
| 9 | Constants estimated from perturbations in C 1Π , B 1Σ+, D 1Π of AgH, and b 1 of AgD; vibrational numbering uncertain. +150 ≤ A ≤ +200. |
| 10 | Approximate constants for the deperturbed state. Perturbations in v=0,1,2 are caused by a 3Π. AgH: ΔG(1/2)= 1519, ΔG(3/2)= 1453; AgD: ΔG(1/2)= 1056, ΔG(3/2)= 987. |
| 11 | Anomalous potential curve; see Learner, 1962. Constants for higher vibrational levels of AgH in Bengtsson and Olsson, 1931, Bengtsson-Knave, 1932. The constants for AgD are valid for v ≤ 4. |
| 12 | Higher order terms are needed to represent levels with v ≥ 4; see Bengtsson and Olsson, 1931, Bengtsson-Knave, 1932, Gero and Schmid, 1943. |
| 13 | RKRV potential curve Singh and Rai, 1965. |
| 14 | H0= +88E-10(AgH); H0= +6E-10 (AgD). |
| 15 | Graphical Birge-Sponer extrapolation of X 1Σ+. Thermochemical value 2.49 eV Farkas, 1929. |
| 16 | From the value for AgH. |
| 17 | Constants refer to unperturbed regions near J=0. Small Λ-type doubling. |
| 18 | R,P much weaker than Q branches. |
| 19 | Approximate constants for the deperturbed state. v=0 strongly perturbed by more than one state. Origin of 0-0 band (not observed) at 46794 cm-1. |
