    • To obtain a reasonable impression of the reaction kinetics one needs to consider not only the highest single activation barrier of a reaction pathway or cycle as the only rate determining criterion. It is necessary to evaluate the complete energy profile including seemingly inactive and/or energetically low lying species. In a series of publications by Shaik and Kozuch and also later by Campbell and co-workers the systematic mathematical description was derived. Shaik and Kozuch designated their model as the so-called energetic span model: a
