摘要:

我们报告的光缔合光谱探测的$c^3Σ_{1}^+$潜力的双碱金属氯化钠分子,确定11个振动线之间的$v' = 0$和$v' = 25$的激发$c^3Σ_{1}^+$潜力,并解决其旋转和超精细结构。所观察到的线被分配通过拟合到一个有效的哈密顿模型的激发态结构的旋转和超精细常数作为自由参数。我们讨论了意想不到的扩大选择振动线,其可能的联系强自旋轨道耦合的$c^3Σ_{1}^+$潜在的附近$b^3Π_1$和$B^1Π_1$流形。最后,我们报告使用的$v' = 22$线作为一个中间状态的弱结合Feshbach分子的双光子转移的振转基态的$X^1Σ^+$流形。

英文摘要:

We report on photoassociation spectroscopy probing the $c^3Σ_{1}^+$ potential of the bi-alkali NaCs molecule, identifying eleven vibrational lines between $v' = 0$ and $v' = 25$ of the excited $c^3Σ_{1}^+$ potential, and resolving their rotational and hyperfine structure. The observed lines are assigned by fitting to an effective Hamiltonian model of the excited state structure with rotational and hyperfine constants as free parameters. We discuss unexpected broadening of select vibrational lines, and its possible link to strong spin-orbit coupling of the $c^3Σ_{1}^+$ potential with the nearby $b^3Π_1$ and $B^1Π_1$ manifolds. Finally we report use of the $v' = 22$ line as an intermediate state for two-photon transfer of weakly bound Feshbach molecules to the rovibrational ground state of the $X^1Σ^+$ manifold.
