项目摘要

The majority of our knowledge of the astronomical world is derived from the emission, absorption,and scattering of electromagnetic radiation from atoms and molecules. The astronomical observationsof atomic and molecular spectra including transition energies, intensities, and light polarizationcomplemented with laboratory experiments and theoretical calculations are essential in the study ofstellar atmospheres. The goal of this CNIC proposal is to catalyze an international interdisciplinarycollaboration between the group of Prof. Ludwik Adamowicz, at the Department of Chemistryand Biochemistry, the University of Arizona (USA) and Prof. Jow-Tsong Shy, at the Departmentof Physics, the National Tsing Hua University (Taiwan) on performing very accurate experimentaland theoretical studies of the rovibrational (rovib) spectra of small hydrogen-containing moleculesand clusters. These systems constitute a significant portion of the mass of the universe and arekey to the interstellar chemistry. The goal of this collaborative is to characterize and assign therovibrational spectra of the studied molecular systems. The obtained data can be very helpful inidentifying spectral lines recorded by telescopes and assigning these lines to particular molecules andclusters. As a result, knowledge will be gained about the compositions of various domains in theuniverse and about chemistry occurring there.This collaboration brings together groups with very different research profiles. The Taiwangroup has been concerned with high-precision experimental spectroscopy studies of small neutral andcharged molecular systems. The theoretical-chemistry Arizona group has been involved in developmentand application of very accurate quantum-mechanical methods for calculating spectra of small atomsand molecules. Both groups are accomplished in their respective fields. In this project, the theoryand the experiment will be combined in elucidation of the spectra of molecules and clusters involvinghydrogen and its isotopes. The studies are very fundamental in nature and as such they are wellsuited for NSF funding.

我们对天文世界的大部分知识都是从原子和分子的电磁辐射的发射，吸收和散射中得出的。原子和分子光谱的天文观察值包括过渡能，强度和通过实验室实验和理论计算的光偏振化，这在史密斯大气层的研究中至关重要。 The goal of this CNIC proposal is to catalyze an international interdisciplinarycollaboration between the group of Prof. Ludwik Adamowicz, at the Department of Chemistryand Biochemistry, the University of Arizona (USA) and Prof. Jow-Tsong Shy, at the Departmentof Physics, the National Tsing Hua University (Taiwan) on performing very accurate experimentaland theoretical studies of the rovibrational (rovib)含氢的小分子和簇的光谱。这些系统构成了宇宙质量的很大一部分，并且是星际化学的质量。该协作的目的是表征和分配研究分子系统的治疗光谱。获得的数据可以非常有助于远程记录的光谱线，并将这些线分配给特定的分子和clus子。结果，将获得有关Universe中各个领域以及在那里发生的化学反应的组成的知识。该协作汇集了具有截然不同的研究概况的群体。 Taiwangroup一直与小型中性和指控分子系统的高精度实验光谱研究有关。亚利桑那州的理论化学组已参与开发和应用非常准确的量子力学方法来计算小原子和分子的光谱。两组在各自的领域都完成。在这个项目中，理论和实验将结合阐明涉及氢及其同位素的分子和簇的光谱。这些研究本质上是非常基本的，因此它们可以用于NSF资助。
