8From a perturbation in v=0 of c 1.
9Deperturbed constants; v=0 interacts with Omega = 2(v=0), v=1 with B 3Pi0+(v=2). Omega-type doubling Deltanuef(v=0) ~ +0.055J(J+1).

16Predissociation above v=0, J=0 Herzberg and Mundie, 1940 caused by an unstable 3Sigma+ state from Cu, 2S + H, 2S See also Kleman, 1953.
17Extrapolation of A 1Sigma+ to the limit Cu(2D5/2) + H(2S). Predissociation in A 1Sigma+ gives < 2.89 eV, flame photometry Bulewicz and Sugden, 1956 2.86eV.
