论文摘要
高分辨率傅立叶变换光谱和激光诱导的荧光已在红外光谱范围内进行。我们分析了$（2）^2σ^+$ - $ x（1）^2σ^+$ lica系统的Rovbibrational Transitions，并找到$（2）^2σ^+$ state to spin-Orbit耦合到$（1）^2π$状态。我们研究了$（2）^2σ^+$和$（1）^2π$状态的耦合系统，以及有效的自旋轨道和自旋旋转偶联常数。还通过应用潜在函数而不是对状态$（2）^2σ^+$的反振动分子参数来评估耦合系统。由于观察到的旋转阶梯的扩展，得出了$ x（1）^2σ^+$状态的改进的分析势函数。
High resolution Fourier transform spectroscopy and Laser induced fluorescence has been performed on LiCa in the infrared spectral range. We analyze rovibrational transitions of the $(2)^2Σ^+$--$X(1)^2Σ^+$ system of LiCa and find the $(2)^2Σ^+$ state to be perturbed by spin-orbit coupling to the $(1)^2Π$ state. We study the coupled system obtaining molecular parameters for the $(2)^2Σ^+$ and the $(1)^2Π$ state together with effective spin-orbit and spin-rotation coupling constants. The coupled system has also been evaluated by applying a potential function instead of rovibrational molecular parameters for the state $(2)^2Σ^+$. An improved analytic potential function of the $X(1)^2Σ^+$ state is derived, due to the extension of the observed rotational ladder.
