Fifty four N-(i,j-disubstituted phenyl)-4-substituted benzenesulphonamides of the general formula 4-X’C 6 H 4 SO 2 NH(i,j-X 2 C 6 H 3 ), where X’ = H, CH 3 , C 2 H 5 , F, Cl or Br; i,j = 2,3; 2,4; 2,5; 2,6 or 3, 4; and X = CH3 or Cl, are prepared and characterized and their infrared,  1 H and  13 C NMR spectra in solution are studied. The N-H stretching vibrations νN−H absorb in the range 3305 - 3205 cm −1 , while the asymmetric and symmetric SO 2  vibrations vary in the ranges 1377 - 1307 cm −1  and 1184 - 1128 cm −1 , respectively. The N-(i,j-disubstituted phenyl)-4-substituted benzenesulphonamides show C-S, S-N and C-N stretching vibrations in the ranges 844 - 800 cm −1 , 945 - 891 cm −1  and 1309 - 1170 cm −1 , respectively. The compounds do not exhibit particular trends in the variation of these frequencies on substitution either at ortho or meta positions with either a methyl group or Cl. The observed  1 H and  13 C chemical shifts of
