| Abstract: | The high dispersion absorption spectrum of the Ag2 molecule has been photographed in the ～5300–1500-Å region. Observations include the previously reported A ← X, B ← X, C ← X, D ← X, and E ← X transitions and a new H ← X transition which occurs in the vacuum ultraviolet. Extensive spectral blending precluded detailed rotational analyses, but the band structures are consistent with and for D-X and C-X, respectively. The H state is perturbed and probably predissociated. The following molecular constants (in cm?1) were obtained from fitting bandhead data to the usual expressions: | State | Te | ωc | Xωt | | X | 0.0 | 192.0 | 0.58 | | B | 35 838.6 | 151.8 | 0.87 | | C | 37 631.6 | 171.0 | 0.84 | | D | 39 014.5 | 168.2 | 1.20 | | E | 40 159.9 | 146.1 | 1.58 | | H | 58 273.1 | 165.9 | 2.46 |
