A study on molecular heteroconjugation equilibria modelling acid-base interactions in polipeptydes by using ab initio and potentiometric methods

摘要

Processes of hydrogen bond formation and proton transfer belong to the most important and most frequently studied chemical processes.Acid-base interactions involving proton transfer are of paramount importance for stabilisation of structures and functioning of biomolecules.One of the steps of virtually each reaction in organic chemistry is a complete or partial proton transfer.For example,in polar aprotic solvents and in amphiprotic ones exhibiting weak tendency towards proton exchange,in systems containing bases B and molecular acids HA.apart from acid dissociation and homoconjugation,also equilibrium of molecular heteroconjugation has to be considered
