论文摘要
星际介质中分子的异构主义及其背后的机制是空间中有机分子化学中的重要问题。特别是，对于简单的甲酸和硫代甲酸，分子云中发现的低温表明必须阻碍气相中的顺式跨性别异构化。发生在星际粉尘颗粒顶部的反应可能解释了低温下的异构体互连。我们研究了易感的甲酸和硫代甲酸的异构化过程发生在星际粉尘粒的表面，并由H抽象反应引发。同样，可以通过相同的机制出现酸的氘富集。我们的目标是阐明这两个主题，以增加我们对空间中有机分子的关键前体的理解。
The isomerism of molecules in the interstellar medium and the mechanisms behind it are essential questions in the chemistry of organic molecules in space. In particular, for the simple formic and thioformic acids, the low temperatures found in molecular clouds indicate that cis-trans isomerization in the gas-phase must be impeded. Reactions happening on top of interstellar dust grains may explain the isomer interconversion at low temperatures. We studied the isomerization processes of formic and thioformic acid susceptible to happen on the surface of interstellar dust grains and initiated by H abstraction reactions. Similarly, deuterium enrichment of the acids can occur by the same mechanism. Our objective is to shed light on both topics to increase our understanding of key precursors of organic molecules in space.
