35Cl nuclear quadrupole resonance studies of hydrogen bonding in solid complexes of chlorobenzoic acids with amines
Abstract
35 Cl nuclear quadrupole resonance studies of hydrogen-bonded adducts containing o-, m- and p-chlorobenzoic acid and 2,6-dichlorobenzoic acid have been carried out. Average frequencies are correlated with ΔpKa values in terms of the proton-transfer model. The results obtained for various proton donors are compared and discussed taking into account both intra- and inter-molecular effects.
