✦ Synopsis

Abstract

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 ^1^J(C‐α,H) has led to a determination of additive increments, ζ, for the functional groups NH~3~, NHCO, COO^−^, and CONH which can be used, together with known values for NH~2~, COOH and alkyl substituents, to calculate ^1^J(C‐α,H) in amino acids and peptides.

## Abstract ^1^__J__(^15^N^13^C) values obtained from FT ^13^C NMR spectra were measured for a number of ^15^N‐enriched aniline derivatives and are found to exhibit varying degrees of dependence on the nature of the ring substituent. Theoretical calculations of ^1^__J__(^15^N^13^C) values for repre
