The chemical shifts at infinite dilution and coupling constants of some meta ‐substituted nitrobenzenes (C 6 H 4 NO 2 X) were determined in CDCI 3 solutions (X = CHO, OCH 3 , CI, Br, NH 2 , NO 2 ) and in CCI 4 solutions (X = OCH 3 , CI, Br). Substituent effects on the chemical shift of the meta ‐hydrogen are analysed in terms of existing theories.
