New Rydberg-Rydberg Transitions of the ArH and ArD Molecules

We report observations and analyses of bands in the spectra of the ArH and ArD molecules due to emission from the 4f Rydberg complexes. For ArD, the observed bands are 4f --> 5s and 4f --> 3dlambda for all three components lambda = 0, 1, and 2 of the 3d state. These give direct information on all 14 spin-orbit components of the 4f complex. For ArH, the data… CONTINUE READING
