Theoretical study of spectroscopic constants and transition properties of silicon hydride cation

The potential energy curves and dipole moments for the lowest seven Λ−S states correlating to three dissociation limits Si+(P2u)+H(Sg2), Si+(Pg4)+H(Sg2), and Si(Dg1)+H+(Sg1) of SiH+ cation are computed using multi-reference configuration interaction plus Davidson corrections method with the AWCV5Z-DK basis set. By solving the radical Schrödinger equation, the spectroscopic parameters of these states are obtained, which are in excellent agreement...
