Mini-Symposium: Spectroscopic Perturbations
Scientific paper
Transition-metal containing molecules, in general, have a high density of electronic states even in the energy region of the electronic ground state. Often the pure rotational spectrum of these species exhibits perturbations caused by low-lying excited states. Examples of these perturbations include irregular spin-orbit, fine structure, and hyperfine patterns. A good example of a molecule exhibiting some of these perturbations is VCl^+. This species has a ^4Σ^- ground state, but has unusually large spin-spin splittings. These perturbations indicate that the ground state is interacting with the excited ^4Π_i and/or ^2Π_i states. A deperturbation analysis of the rotational spectrum of VCl^+ is currently underway, and the results of this analysis will be presented.
