abstract = {<p style="text-align: justify;">By using multi-reference configuration interaction method and large all-electron
basis sets aug-cc-pwCV5Z, we have calculated the dense potential energy
curves (PECs) of $1¹Σ^+,$ $1³Σ^+,$ $1¹\Pi,$ and $1³\Pi$ states of $LiBe^+$ molecule. Based on the obtained
PECs, the analytical potential energy functions (APEF) have been constructed
with a Morse long-range potential function and nonlinear least squares method. The
rotational and vibrational energy levels of the four states are determined by solving
Schrödinger equation of nuclear movement with the APEFs. The spectroscopic parameters
are deduced with the obtained rotational and vibrational energy levels.</p>},
