Laser cooling of OH molecules in theoretical approach
采用高精度的多参考组态相互作用方法计算OH分子基态和第一激发态的势能曲线.为获得更精确的计算结果,在计算过程中考虑Davidson修正、标量相对论效应、核价相关效应和自旋轨道耦合效应.基于计算的 Λ-S和 ? 态的势能曲线,对一维径向薛定谔方程进行数值求解,得到各个电子态的光谱数据,与已报道的实验值和理论值相符合.获得OH分子的永久偶极矩、跃迁偶极矩、振动能级、Franck-Condon因子及辐射寿命,结果表明,A2Σ+→X2Π 跃迁具有高度对角…查看全部>>
Ultracold molecules have wonderfully potential applications in quantum system, precision measurement, and chem-ical dynamics, and so on. Thus, people have a strong desire for investigating the potential cooling candidates. Feasibility of laser cooled OH molecules is investigated by ab initio quantum chemistry. Potential energy curves for the ground state X2Π and low-lying excited state A2Σ+ of OH molecules are calculated by multi-reference configuration inte…查看全部>>
