## Abstract A series of ^15^N labeled 2βacylpyrroles was prepared and the nitrogen and proton n.m.r. spectra obtained. ^15^N chemical shifts for these compounds are reported for the first time. No correlation between the nitrogen chemical shift and any Hammett substituent constant could be found. N
