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.

这是一个持续的项目，结合天文学和实验室研究简单分子离子的分子光谱学。 将朝着若干方向努力。 1)将继续进行H3+和相关分子的天文光谱学研究，以便更全面地揭示弥漫星际介质的化学性质。 2)基于计算机控制的色心激光器的新型离子谱仪将用于天体物理学感兴趣的分子离子（如C_3H_3 ~+、CH_2NH_2 ~+等）的振动旋转光谱。3）实验室光谱学将被推到更短的波长区域，以对应从在稠密云中的天文观测到扩散云的变化。 H3+的泛音是理论研究的基准，将是新测量的第一个焦点。 这个多学科项目由数学和物理科学局的物理，化学和天文科学部门共同支持。
