Abstract

We establish a theoretical model to analyze the photoassociative (PA) spectroscopy of (3)³Σ⁺ state of ⁸⁵Rb¹³³Cs molecule. The term energy, spin-spin coupling constants and hyperfine interaction constant of nine vibrational levels in the (3)³Σ⁺ state are determined. Based on the fitted term energy and rotation constant, the potential energy curve of (3)³Σ⁺ state is obtained by using the RKR method which is compared with the ab initial potential curve.
