| 16 | Predissociation above v=0, J=0 Herzberg and Mundie, 1940 caused by an unstable 3Σ+ state from Cu, 2S + H, 2S See also Kleman, 1953. |
| 17 | Extrapolation of A 1Σ+ to the limit Cu(2D5/2) + H(2S). Predissociation in A 1Σ+ gives < 2.89 eV, flame photometry Bulewicz and Sugden, 1956 2.86eV. |
| 18 | From a combination of Ringstrom's data for v=0, 1, 2 and Heimer's data for v=3, 4. ωeye= +0.067, γe= +0.0015. |
