Stability and protonation of multielectron systems: The concept of proton affinity. I. Vague limits


  • This article is dedicated to Sylvio Canuto on the occasion of his 60th birthday.


The present work is a kind of a “polyphonic” collection of thoughts about the relationship between the stability of multi-electron systems and the protonation. The intricacy of the protonation sites and the protonated states that are absorbed into the concept of the proton affinity is discussed, particularly addressing its range of validity. This work can also be considered as an attempt to have a look “at different angles” at one of the most important molecular processes that occur in nature and that are reflected in our mirror of the perception of nature. © 2010 Wiley Periodicals, Inc.
