Differences in the distribution of deuterium at individual atomic sites in vanillin samples are revealed by 2H-NMR measurements, and can be used to determine whether the sample is of natural or synthetic origin.

Empirical factors I(C) have been evaluated from experimental 1 J(C,C) data for a variety of structural fragments. It is also shown how I(C) factors can be obtained from 1 J(C,H) or from Malinowski's ξ increments. The product of such I(C) values repr

Conformational effects on the one-bond Cα, H coupling constant have been studied in cyclic oligopeptides containing glycine, alanine, sarcosine and proline. The conformational contribution to 1J (Cα, H) can be described as being composed of a posit

One-bond C-α,H coupling constants are reported for glycine, alanine, sarcosine and related di- and tripeptides. A detailed study of the pH dependence of 1J(C-α,H) has led to a determination of additive increments, ζ, for the functional groups NH3,

Carbon-hydrogen spin coupling constants over one bond, 1J(C,H),were determined for a number of simple open-chain model peptides as well as for cyclo-disarcosyl, cyclo-tetra-sarcosyl and cyclo-octasarcosyl. The dependence of 1J(Cα,H) on the ionizatio
