## Abstract The ^15^N^13^C coupling constants of ^15^N‐enriched acetamide, __N__‐acetylglycine anilide, phthalimide, α,α′‐bisphthalimido‐__p__‐xylene, __N__‐methyl‐__N__′‐phenylurea, poly‐L‐alanine and poly‐L‐valine were measured in various solvents. It was found that the ^15^N^13^C coupling cons
