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 0096491 Herbst分子存在于宇宙中许多不同的环境中，是探测其周围环境的绝佳探针。 分子光谱特征的分析产生了重要的信息，但更全面的分析需要将许多观测结果与各种来源的详细化学和物理模型进行比较。 在一项持续的研究计划中，俄亥俄州州立大学的埃里克·赫布斯特博士希望了解并利用化学来解释和指导分子的天文观测，并更好地了解各种星际和环星物体。 在此期间，Herbst博士将进行各种各样的建模研究，同时改进他的标准气相和气体颗粒模型。 他将特别关注星际云中恒星形成区域的环境。 他还将专注于提高他的粮食表面化学，因为新的实验和理论现在开始带来一些理解这一领域。 ***
