AST 0096491HerbstMolecules are found in many different environments in the Universe and are excellent probes of their surroundings. Analysis of molecular spectral features yields important information, but more comprehensive analysis requires the comparison of many observations with detailed chemical and physical models of the assorted sources. In a continuing research program, Dr. Eric Herbst, at the Ohio State University, hopes to understand and utilize chemistry to explain and guide astronomical observations of molecules, and to better our understanding of assorted interstellar and circumstellar objects. During this award period, Dr. Herbst will pursue a wide variety of modeling studies, with concomitant improvements to his standard gas-phase and gas-grain models. He will pay particular attention to the environments of star-forming regions of interstellar clouds. He will also concentrate on improving his grain surface chemistry, since new experiments and theories are now beginning to bring some understanding to this field. ***

AST 0096491HERBSTMOLECULES在宇宙的许多不同环境中都发现，并且是周围环境的极好探针。 分子光谱特征的分析产生了重要信息，但是更全面的分析需要将许多观察结果与各种来源的详细化学和物理模型进行比较。 在继续研究的计划中，俄亥俄州立大学的埃里克·赫布斯特（Eric Herbst）博士希望理解并利用化学来解释和指导分子的天文观察，并更好地理解我们对各种星际和情节对象的理解。 在此奖项期间，Herbst博士将进行各种建模研究，并将其标准的气相和气体元素模型进行改进。 他将特别注意星际云的星形区域的环境。 他还将集中精力改善谷物表面化学反应，因为新的实验和理论现在开始对这一领域有所了解。 ***
