Calculating vibration-rotation spectrum intensities of laser-induced fluorescence for the B1Π - Χ1Σ+ electronic transition in a LiCs molecule

The purpose of this study was to calculate the intensities of the vibration-rotation spectrum of laser-induced fluorescence for the B1Π - Χ1Σ+ electronic transition in a LiCs molecule. We find vibration-rotation energies and wave functions as a result of numerically solving the radial wave equation based on potential energy curves plotted in the present work for the ground and excited states. We compare calculated and experimental intensities.
