论文摘要
我们建立了一个理论模型,以分析$(3)^3σ^+$ $^{85} $ rb $^{133} $ CS分子的光相关(PA)光谱。确定了$(3)^3σ^+$状态中9个振动水平的术语能量,自旋旋转耦合常数和超精细相互作用常数。基于拟合项的能量和旋转常数,通过使用与AB初始电势曲线进行比较的RKR方法获得$(3)^3σ^+$状态的势能曲线。
We establish a theoretical model to analyze the photoassociative (PA) spectroscopy of $(3)^3Σ^+$ state of $^{85}$Rb$^{133}$Cs 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.
