A MRCI study of the low-lying electronic states of the BeAl molecule

In this work is presented, for the first time, an accurate spectroscopic characterization of the lowest-lying doublet and quartet states of BeAl molecule. We used a high level CASSCF/MRCI correlation methodology and the aug-cc-pVQZ basis set. The behavior of the dipole moment and the transition dipole moment functions are described, and transition probabilities and radiative lifetimes are also predicted using the Einstein coefficients.
