摘要：
The potential energy surface for the electronic ground state of the HXeBr molecule is constructed from more than 4200 ab initio points calculated using the internally contracted multi-reference configuration interaction method with the Davidson correction(icMRCI + Q).The stabilities and dissociation barriers are identified from the potential energy surface.The three-body dissociation channel is found to be the dominant dissociation channel for HXeBr.Low-lying vibrational energy levels of HXeBr calculated using the Lanczos algorithm are found to be in good agreement with the available experimental band origins.
