We report on extensive calculations of quasi-relativistic potential energy curves and, for the first time, transition dipole moments including spin-orbit and scalar-relativistic effects of the NaRb molecule. The calculated curves of the 0⁺$0^{+}$, 0^-$0^{-}$, 1, 2 and 3 molecular states correlate for large internuclear separation with the fourteen lowest atomic energies up to the Na(3s²${\mathrm{s}}^2$S_1/2${\text{S}}_{1/2}$)+Rb(7s²${\mathrm{s}}^2$S_1/2${\text{S}}_{1/2}$) atomic limit. Several new features of the potential energy curves have been found.

NaRb的相对论势能曲线和跃迁偶极矩

我们报道了准相对论势能曲线的大量计算，并且首次报道了过渡偶极矩，包括NaRb分子的自旋轨道和标量相对论效应。0 ⁺的计算曲线$0^{+}$，0 ^-$0^{--}$，1、2和3的分子状态与大的核间分离相关，且直至Na（3 s ^2）的原子序数最低的十四^个${\mathrm{s}}^{\mathrm{2个}}$小_1/2${\text{小号}}_{\mathrm{1个}/\mathrm{2个}}$）+ Rb（7 s ²${\mathrm{s}}^{\mathrm{2个}}$小_1/2${\text{小号}}_{\mathrm{1个}/\mathrm{2个}}$）原子极限。已经发现势能曲线的几个新特征。
