Abstract
IN continuation of earlier work1 we have investigated the absorption spectrum of inorganic sulphates and of ammonium nitrate in the vapour state. The same method was employed, but that the SO2 bands were used as indicator of decomposition of the sulphates. The observed maxima of selective absorption are as follows (in m): H2SO4 262, K2SO4 258, Ag2SO4 265, and ZnSO4 269. The red wave limits are 285, 293, 300 and 294 m respectively.
