15N NMR data are reported for two Di-(alpha-pyridyl) derivatives in various stages of protonation. A combination of 15N NMR measurements taken, on a number of solutions, and on the solid state provide a quantitative overall view of the progress of protonation of these compounds. 15N shieldings, J(15

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
Tensor evaluations of biological polymers are usually bisphthalimide compounds. The 15 N CSA tensor elements (d 11 , based on labeled-model-compound studies; thus, a series of d 22 , and d 33 ) for the labeled derivatives were determined from CSA labeled model imide compounds based on the phthalimid
