摘　　要：Vibrational transition spectra of H2＋ in an ultra-strong magnetic field are determined. The validity of Born- Oppenheimer approximation is analyzed based on one-center method and B-spline basis sets. It is shown that Born- Oppenheimer approximation is reliable for the investigation on the ground state and low excited states of H2＋ subjected to the strong magnetic field. Furthermore, it is found that the vibrational transition spectra from lσg, lπu, and 1δg states lie in infrared, visible, and ultraviolet ranges with increasing magnetic field strength.Vibrational transition spectra of H2＋ in an ultra-strong magnetic field are determined.
