Abstract
The enthalpies of protonation of polyamines in aqueous solution are interpreted in terms of a simple model that does not involve any tautomeric equilibrium. The enthalpies are calculated as the sum of two contributions; bond formation enthalpy (E B ) and solvation enthalpy (E S . The results agree well with experimental data.
