“…While for weaker, higher excited electronic states, and more sophisticated transition structures, it is difficult to obtain. Many mature experimental techniques have been developed in the past 20 years to obtain the transition spectra of some diatomic molecules in these electronic states and conduct in-depth analysis and research [30][31][32]. However, due to the limitations of the experimental equipment itself and the instability of the high rovibrational excited states of most diatomic molecules, it is a chanllenge to obtain the transition spectral lines of high rovibrational excited states by the existing experimental techniques.…”

Starting from the classical expression of the rovibrational transition spectra of diatomic molecule, the Difference Converging Method (DCM) is used again to derive a new convenient and easy-to-use analytical formula for predicting the P-branch transitional spectral lines in the highly rovibrational excited states of diatomic molecule. Based on the limited experimental low-lying transition spectra the emission spectral lines up to the rotational quantum number J = 80 of (0–0) band in the A Π 3 A 2 0 + → X 3 ∑ − X 1 0 + , X 2 1 transition systems of BiLi molecule are predicted and studied. The accuracy of prediction is analyzed in detail by using the prediction error Δδ, which gives a quantitative conclusion for the reliability of prediction data. Compared the data obtained by DCM method with experimental ones, and analyzed the v E x p t − v D C M , Δ E x p t , Δ D C M , Δ δ in deeply, the results show that the DCM method can use 11 known P-branch emission spectral lines to reliably reproduce the experimental values and accurately predict the high-excited transition spectral lines which may be difficult obtained in the experiment. It provides a new method to solve the problem of lack of high excited state transition spectra of diatomic molecules and the application of molecular spectrum in other fields.
