## Abstract Residual dipolar splittings in ^13^C crossβpolarization magicβangle spinning spectra arising from coupling to chlorine nuclei are reported for the three chloroacetanilide isomers, using several spectrometers. At medium to high magnetic field doublets are seen for Cο£ΏCl carbon resonances.
The 13 C cross-polarization magic angle spinning NMR spectra of various nitroanilines and some other N-containing compounds were measured and the differential broadening between the signals split by the residual dipolar interaction with 14 N was investigated. The dipolar interaction between 14 N and
