## Abstract The dipeptide alanylproline has been prepared with the proline residue both ^13^C (15%) and ^15^N (95%) enriched. ^15^N NMR spectra of alanylproline reveal signals for both possible conformations—__cis__ and __trans__—of the dipeptide backbone in solution. Different p__K__ values for bo
## 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
## Abstract Geminal ^15^N^13^C coupling constants have been measured in a series of ^15^N‐enriched 1‒phenyl‒3,5‒dialkyl‐substituted pyrazoles. The importance of the orientation of the nitrogen lone‐pair in determining the magnitude of ^2^__J__(^15^N^13^C) values is reflected in the enhanced coupli
