A simple relation between 1H NMR data and mixing enthalpy for systems with complex formation by hydrogen bonding
Original language description
enthalpy has been found for systems that form 1:1 complexes by hydrogen bonding. Starting from relatively general assumptions, we havederived two forms of this relation. The first form is represented by proportionality between the solution enthalpy of the proton-donor and the chemical shift change of its active hydrogen atom. The second form is mediated by the relative extent of hydrogen bond formation , a quantity which can be directly evaluated from measurements of either the 1H NMR chemical shift orthe mixing enthalpy. The validity of both relation forms has been convincingly demonstrated for 12 systems formed by a strong proton donor (halothane [1-brom-1-chlor-2,2,2-trifluorethane] or trichloromethane) and an oxygen- or nitrogen-containing proton -acceptor (aliphatic
