Note this is a joint CAS/Phys Chem RIG seminar.

We generally think of reactions in the lower part of the Earth’s atmosphere to involve fully thermalized reagents. However, recent work (both experimental and theoretical) in Leeds and elsewhere (e.g. Science 2012, 337, p1066) have shown that reactions of non-thermalized reagents are relevant and that such chemically activated reagents can be generated from both abstraction and addition reactions. In this talk we will consider examples which influence product distributions in the atmosphere (e.g. OH/C2H2/O2) and in field instruments (e.g. influencing HOx measurements) and also consider implications in other environments, for example oxy-fuel combustion (proposed to facilitate carbon capture and storage).
