Interdisciplinary Studies of H3+: Precision Spectroscopy, Reaction Dynamics, and Astronomical Observations

在这项研究中，实验室研究和天文观测都将与H3+有关，H3+是具有两个以上原子的最简单分子。 H3+的红外光谱将以创纪录的精度进行测量，从而能够对理论计算进行新的测试。 H3+与分子氢（H2）的反应将在最低温度下进行测量，以探测有趣的量子力学效应并支持天文观测。 还将测量较大氢离子H5+的红外光谱，以提供对上述反应的约束。 在天文学方面，将使用大型望远镜测量恒星之间各种气体云中H3+的丰度，并将模拟H3+与H2反应对星际H2和H3+的影响。由于其跨学科性质和新实验方法的发展，预计该计划将产生更广泛的影响。 研究生和本科生都将在天体化学的年轻跨学科领域进行培训。 将继续通过开发新的天体化学课程促进研究与教育的结合。 天体化学系列研讨会和区域天体化学联合会的组织将鼓励那些认为自己主要是物理学家、化学家或天文学家的科学家之间的互动。

In this investigation, both laboratory studies and astronomical observations will be performed related to H3+, the simplest molecule with more than two atoms. The infrared spectrum of H3+ will be measured with record precision, enabling new tests of theoretical calculations. The reaction of H3+ with molecular hydrogen (H2) will be measured at the lowest temperatures yet, to probe interesting quantum mechanical effects and support astronomical observations. The infrared spectrum of the larger hydrogen ion H5+ will also be measured to provide constraints on the reaction mentioned above. In terms of astronomy, large telescopes will be used to measure the abundance of H3+ in various clouds of gas between the stars, and the effect of the reaction of H3+ with H2 on interstellar H2 and H3+ will be modeled.This program can be expected to have several broader impacts because of its interdisciplinary nature and its development of novel experimental approaches. Both graduate and undergraduate students will be trained in the young interdisciplinary field of astrochemistry. The integration of research and education will continue to be fostered through the development of new courses in astrochemistry. Interactions between scientists who consider themselves primarily physicists, chemists, or astronomers will be encouraged by an astrochemistry seminar series and also through the organization of a regional astrochemistry consortium.
