Notes

1For the natural isotopic mixture 107Ag/109Ag.
2The Ω-type doubling observed in the 1/2 → 1/2 transitions of A → X and B → X is approximately given by Be= 0.029(J+1/2)-... and Be= 0.022(J+1/2) - ..., respectively.
3Predissociation above v=0, J=66 1/2 in A 2Π1/2 and above v=0, J=73 1/2 in A 2Π3/2. No bands involving v'=2 have been observed.
4Not quite certain that this is the ground state. It appears to be regular with A ~+135 cm-1, contrary to expectations; see Cheetam and Barrow, 1967.
5Thermochemical value (mass-spectrom.) Smoes, Mandy, et al., 1972.
