The splitting phenomenon of the carbonyl absorptions and the shifts of S-N stretching vibrations to a longer wave length region of some N-acyl-N-substituted-sulfonamide derivatives measured in solid state were described. Tertiary sulfonamides had their SO2 stretching vibrations at a shorter wave length region than secondary sulfonamides. N-Acetyl-N-alkylmethane (or ethane) sulfonamide showed strong C-N stretching vibrations of the group N-CH2-R at about 1125cm-1. N-Acyl-N-substituted-sulfonamide derivatives had very strong asymmetric stretching vibrations of the group C-CO-N at 1250∼1290cm-1. Synthesis of some sulfonamide derivatives is also described.
