Molecular Processes on Surfaces of Interstellar Grains

芝加哥伊利诺伊大学的维多利亚·布赫博士正在对星际颗粒表面发生的分子过程进行理论研究。这些过程包括气体颗粒在颗粒上的粘连，脏冰盖在颗粒表面的积聚和解吸，以及颗粒在地幔上和内部的流动。在过去的20年里，星际化学已经成为一个新的令人兴奋的领域，对分子光谱的观测是探测星际云内部的主要诊断工具。在适用于星际云的物理条件下，详细了解分子的形成和破坏过程对于解释观测数据是非常重要的。布赫博士对颗粒分子过程的理论研究将使我们能够更准确、更彻底地解释观测结果。

Dr. Victoria Buch at the University of Illinois, Chicago, is doing theoretical research on molecular processes taking place on the surfaces of interstellar grains. The processes include sticking of gas particles on grains, accumulation and desorption of dirty ice mantles on grain surfaces, and mobility of particles on and within the mantles. Interstellar chemistry has emerged as a new and exciting field during the past 20 years, and observations of the spectra of molecules are a major diagnostic tool for probing the interiors of interstellar clouds. A detailed understanding of the formation and destruction processes of molecules under physical conditions applicable to interstellar clouds is of great importance for the interpretation of the observational data. Dr. Buch's theoretical studies of molecular processes on grains will enable a more accurate and thorough interpretation of observations.
