Using dynamic 15N CPMAS NMR spectroscopy a novel double proton transfer was detected in the cyclic hydrogen bonded dimers of polycrystalline tSN,ZSN'-di-(4-bromophenyl)-formamidine. Rate constants of this process, which is degenerate within the margin of error, were obtained by lineshape (kl2 = 10 6
The 15N results reveal a difference in the extent of intramolecular hydrogen bond formation exhibited by the Schiffs base, compound 2, in solution and the solid state. Comparison of the 15N shielding changes observed, with those arising from protonation, provides the basis for a quantitative estimat
