15 N NMR data of a series of 3‐alkyl[aryl] substituted 5‐trichloromethyl‐1,2‐dimethyl‐1H‐pyrazolium chlorides (where the 3‐substituents are H, Me, Et, n ‐Pr, n ‐Bu, n ‐Pe, n ‐Hex, (CH 2 ) 5 CO 2 Et, CH 2 Br, Ph and 4‐Br‐C 6 H 4 ), are reported. The 15 N substituent chemical shifts (SCS) parameters are determined and these data are compared with the 13 C SCS values and data obtained by MO calculations.
