Hot molecules,which are found in extreme environments such as the edges of fusion reactors, are much more reactive than those used to understand reaction studies at ambient temperature. Detailed knowledge of their reactions is not only relevant to modelling nuclear fusion devices; it is also crucial in simulating the reaction that takes dwelling on a spacecraft's heat shield at the moment when it re-enters soil's atmosphere. Further, and it can help us understand the physics and chemistry of planetary atmospheres.
