对晚型恒星中分子的发射和吸收线观测是我们理解这些天体中的恒星演化、尘埃形成和质量损失的重要组成部分。 AGB恒星星周包层中气体的分子组成反映了气体中的化学过程，其性质是半径的强函数，密度和温度分别变化超过十个和两个数量级。此外，星际紫外线场不仅在确定分子丰度而且在确定其径向分布方面发挥着关键作用。在本文中，我将简要回顾一些最近描述内层和外层化学的成功方法，并概述未来的挑战领域。
Emission and absorption line observations of molecules in late-type stars are a vital component in our understanding of stellar evolution, dust formation and mass loss in these objects. The molecular composition of the gas in the circumstellar envelopes of AGB stars reflects chemical processes in gas whose properties are strong functions of radius with density and temperature varying by more than ten and two orders of magnitude, respectively. In addition, the interstellar UV field plays a critical role in determining not only molecular abundances but also their radial distributions. In this article, I shall briefly review some recent successful approaches to describing chemistry in both the inner and outer envelopes and outline areas of challenge for the future.
