尽管甘氨酸（一种简单的氨基酸，也是地球上所有生命中蛋白质的关键构建模块）存在于陨石、彗星和小行星中，但迄今为止，在星际介质中探测甘氨酸的众多尝试均未成功。甘氨酸具有构象多样性，存在八种不同形式。本文旨在表明，在黑暗环境中，从300 K降至10 K的温度范围内，这些构象之间的相互转化受量子力学隧穿支配，并计算这些变化发生的速率，从而提出建议以最大化成功探测的可能性。
英文摘要
Numerous attempts to detect glycine, a simple amino acid and a key building block of proteins in all life on Earth, in the interstellar medium have so far been unsuccessful in spite of the fact that it is present in meteorites, comets and asteroids. Glycine is conformationally diverse, existing in eight different forms, and the aim is to show that interconversions, in the dark, are governed by quantum mechanical tunnelling at temperatures from 300 K down to 10 K and to compute the rate at which these changes occur resulting in recommendations to maximise a successful outcome.
