稀有气体原子和水分子组成的范德瓦耳斯复合物是研究水和其他原子分子之间相互作用的典型模型.本文利用中红外连续外腔量子级联激光器结合脉冲超声分子束吸收光谱技术,在D2O弯曲振动带(v2展开更多 稀有气体原子和水分子组成的范德瓦耳斯复合物是研究水和其他原子分子之间相互作用的典型模型.本文利用中红外连续外腔量子级联激光器结合脉冲超声分子束吸收光谱技术,在D2O弯曲振动带(v2=1←0)附近测量了Ar-D2O复合物4个新的振动转动子带.基于赝双原子分子有效哈密顿量,本文对测量到的振动转动谱线和前人报道的下能级所涉及的纯转动谱线进行了最小二乘法全局拟合,得到了包括振动子能级能量、转动常数...

The intermolecular interactions involving the water molecule play important roles in many fields of physics, chemistry, and biology. High-resolution spectroscopy of Van der Waals complexes formed by a rare gas atom and a water molecule can provide a wealth of information about these intermolecular interactions. The precise experimental data can be used to test the accuracies and efficiencies of various theoretical methods of constructing the intermolecular potential energy surfaces and calculating the bound states. In this work, the high-resolu...
