Laboratory Study of Reactive Molecules of Interest to Radio and Submillimeter-Wave Astronomy: A Program of Research and Instrumental Development

撒迪厄斯，帕特里克哈弗大学AST-9820722博士。撒迪厄斯和戈特利布将继续对星际气体和星周壳层中的活性分子进行实验室和射电天文研究。这项研究将侧重于分子离子和高活性中性有机分子的傅里叶变换微波(FTM)光谱学和射电天文鉴定。FTM技术是在实验室中确定新分子的存在和确定其丰度的理想手段。这将为在实验室中独立寻找弥散星际带的载体提供关键数据。他们的目标是测量中性物质以及负离子和正离子的射电线路频率，以指导对扩散气体的射电天文观测。他们对关键离子结构的确定将允许评估致密云中特定的离子-分子反应，并提供关于半透明云整体化学方案的重要信息，阐明扩散星际云和致密星际云之间的联系。他们还将继续致力于提高光谱仪的灵敏度。

Thaddeus, PatrickHarvard UniversityAST-9820722Drs. Thaddeus and Gottlieb will continue a program of laboratory and radio astronomical research on reactive molecules in the interstellar gas and in circumstellar shells. The research will emphasize Fourier Transform Microwave (FTM) spectroscopy and radio astronomical identifications of molecular ions and highly reactive neutral organic molecules. The FTM technique is the ideal means for establishing the existence of new molecules in the laboratory and for determining their abundances. It will provide crucial data for an independent search in the laboratory for the carriers of the diffuse interstellar bands. Their goal is to measure radio line frequencies of both neutral species, and also of negative and positive ions, to guide radio astronomical observations of the diffuse gas. Their determination of structures in key ions will allow the assessment of specific ion-molecule reactions in dense clouds, and provide important information on the overall chemical scheme in translucent clouds, elucidating the link between diffuse and dense interstellar clouds. They will also continue work toward increasing the sensitivity of the spectrometer.
