摘要

多年来人们已经知道，分子氧是在非常高的振动状态下由大气中臭氧的光解作用产生的，高度存在的氧可能对大气产生的影响一直是广泛研究的主题。这篇短文描述了关于这个问题的最新实验和理论进展。O2(v > 20)的碰撞动力学现在似乎得到了很好的理解;然而，在更高的振动水平上，在能量上局部于假设的O4络合物和O + O3形成的过渡态，仍然需要做大量的工作。

Chemistry with stretched molecules

It has been known for some years that molecular oxygen is produced in very high vibrational states by the photolysis of ozone in the middle atmosphere and the possible atmospheric implications of highly exicted oxygen have been the subject of extensive investigation. This short article describes the latest experimental and theoretical advances regarding this problem. The collision dynamics of O₂(v≲20) now appears to be well understood; however, at higher vibrational levels, which are energetically local to the hypothesized O₄ complex and to the transition state for O + O₃ formation, much work is still needed.
