TLDR
In this paper, the rotational energy levels of the SH + (sulfoniumylidene) radical in the v ǫ = 0 and 1 levels of X 3 Σ − ground state have been subjected to a single, weighted least-squares fit to determine an improved set of molecular parameters for this molecule.About:

Submillimeter absorption from SH+, a new widespread interstellar radical, 13CH+ and HCl
TL;DR: The Atacama Pathfinder Experiment 12 m telescope (APEX) was used to carry out an absorption study of submillimeter wavelength rotational ground-state lines of H 35 Cl, H 37 Cl, 13 CH +, and, for the first time, of the SH + radical (sulfoniumylidene or sulfanylium) as discussed by the authors.

An effective Hamiltonian for diatomic molecules . Ab initio calculations of parameters of HCl
TL;DR: In this paper, the form of the effective Hamiltonian for a diatomic molecule in an electronic state intermediate between Hund's cases is reexamined, and the formulas for the parameters assist in the comparison with ab initio calculations.
