Abstract
- By the use of a grating spectrometer, the infra‐red absorption spectra of aqueous solutions of five inorganic materials (KI, CuBr2, ZnBr2, CdCl2·2H2O, and NaOH) and six organic materials (acetone, CH3COONa, CH3COONH4, cane sugar, C6H5OH, and C2H5OH) were observed in the region of the water band at 4.72μ. The organic materials investigated caused a displacement of the position of maximum absorption to shorter wave‐lengths; the inorganic materials apparently caused a shift to longer wave‐lengths, but the actual effect on the water band may be masked by other absorption bands in the same region. The concentration‐shift relationship was investigated for some of the materials. Size of the solute molecule and the positive ion seemed to be of comparatively little importance.
