Recent progress in studies of Rydberg double-well electronic energy states of MeNg (Me = 12-group atom, Ng = noble gas atom) van der Waals (vdW) molecules is presented and analysed. The presentation covers approaches in experimental studies as well as ab initio-calculations of potential energy curves (PECs). The analysis is shown in a broader context of Rydberg states of hetero- and homo-diatomic molecules with PECs possessing complex 'exotic' structure. Laser induced fluorescence (LIF) excitation spectra and dispersed emission spectra employed in the spectroscopical characterization of Rydberg states are presented on the background of the diverse spectroscopic methods for their investigations such as laser vaporization-optical resonance (LV-OR), pump-and-probe methods, and polarization labelling spectroscopy. Important and current state-of-the-art applications of Rydberg states with irregular potentials in photoassociation (PA), vibrational and rotational cooling, molecular clocks, frequency standards, and molecular wave-packet interferometry are highlighted.
本文介绍并分析了MeNg（Me = 第12族原子，Ng = 稀有气体原子）范德华（vdW）分子里德堡双阱电子能态研究的最新进展。内容涵盖实验研究方法以及势能曲线（PEC）的从头算计算。在具有复杂“奇异”结构PEC的异核和同核双原子分子里德堡态的更广泛背景下进行了分析。在用于研究里德堡态的多种光谱方法（如激光汽化 - 光共振（LV - OR）、泵浦 - 探测方法和偏振标记光谱）的背景下，展示了用于里德堡态光谱表征的激光诱导荧光（LIF）激发光谱和色散发射光谱。重点介绍了具有不规则势的里德堡态在光缔合（PA）、振动和转动冷却、分子钟、频率标准以及分子波包干涉测量中的重要且当前的前沿应用。
