1H and 13C NMR chemical shift assignments for 11 α‐phenylsulfonylacetanilides and 15N NMR chemical shifts for four representative congeners are reported. The 1H and 13C chemical shift assignments are based on DQF COSY and PFG 1H,13C HMQC/HMBC experiments. The 15N NMR chemical shifts were determined by PFG 1H,15N HMBC experiments. The correlation analyses with Hammett‐type substituent constants gave
