Agreement between theory and practice : Solid‐state NMR studies on organic compounds with CH 2 Cl, CHCl 2 , and CCl 3 groups show that residual dipolar coupling between 35 Cl/ 37 Cl and 13 C nuclei influences the splitting of the signals depending on the magnetic field strength B . When molecular motions are slow enough to prevent self‐decoupling, signals for C nuclei affected by a single Cl nucleus appear as symmetric doublets at B 0 >5 T and as asymmetric triplets at lower fields.
