Molecular Observation in Interstellar Space and Laboratory Spectroscopy of Molecular Ions and Other Exotic Molecules

这是一个结合天文学和简单分子离子分子光谱的实验室研究的持续项目。将采取若干方向。1) H3+和相关分子的天文光谱将继续进行，以便揭示弥漫星际介质的更完整的化学图景。2)基于计算机控制色心激光器的新型离子光谱仪将用于C3H3+、CH2NH2+等具有天体物理意义的分子离子的振动旋转光谱研究。3)实验室光谱将被推进到更短波长区域，以适应从稠密云到弥漫云的天文观测的变化。H3+的泛音是理论研究的基准，将是新测量的第一个重点。这个多学科项目由数理化司的物理、化学和天文科学部联合支持。

This is a continuing project in the combination astronomical and laboratory studies of the molecular spectroscopy of simple molecular ions. A number of directions will be pursued. 1) Astronomical spectroscopy of H3+ and related molecules will be continued in order to reveal a more complete picture of the chemistry of the diffuse interstellar medium. 2) A new ion spectrometer based on a computer-controlled color center laser will be used for vibration rotation spectroscopy of molecular ions of astrophysical interest such as C3H3+, CH2NH2+, etc. 3) The laboratory spectroscopy will be pushed to shorter wavelength regions to correspond to a change from astronomical observation in dense clouds to diffuse clouds. Overtones of H3+, a benchmark for theoretical studies, will be the first focus of the new measurements. This multi-disciplinary project is supported jointly by the Divisions of Physics, Chemistry, and Astronomical Sciences in the Mathematical and Physical Sciences Directorates.
