## Abstract Experimonts conducted during the development of an earlier instrument showed that the acidic sulphur oxides present in washed flue gas were not readily absorbed by hydrogen peroxide solutions, whereas sulphur dioxide was completely absorbed. These experiments have been extended, and by
Infra-ret1 spectra were obt,ained from anhydrons and hydrated sulphonic acids, as well as of the deutcratecl benzenesnlphonic acid. Following assignments of bands characteristic of the sulphonic acitl group are proposed: v(OH) 2900 and 2350 cm-l, u,,(SO,) 1350 cm-', v,~(SO,J 1160 cm-l, r(W) 900 cm-'
