physical chemistry - How does the inverted Marcus region explain chemiluminescence?


The invert Marcus region offers one explanation of chemiluminescence, the process by which light is one of the products of a chemical reaction.


I tried reading one of Marcus's original papers on the subject [1], but I don't really get his argument. I get confused about which of the potential energy surfaces in his Figure (copied here, hopefully that's okay) that refer to the ground state reactant, ground state product, excited reactant, and excited product.

Apparently the of last four, $\ce{Mg^2+}$ is closest in radius to $\ce{Li+}$. Is this true, and if so, why would a whole larger shell ($\ce{...
