## Abstract We report the determination of two‐ and three‐bond ^1^H‐^15^N spin–spin couplings in the nmr spectra of a polypeptide. The ^1^H‐ and ^15^N‐nmr spectra of 99.2% ^15^N‐enriched alumichrome have been studied at 360 MHz and 10.1 MHz, repectively. While some ^2^__J__ and ^3^__J__ coupling ar
