Abstract

Sensitive techniques based upon the thermooptic effect are now available to measure weak absorptivities α of solutions (α ~ 10⁻³ cm⁻¹). In many cases the detection of trace amounts of dissolved material is complicated by large background absorptions (α ~ 10⁻³ cm⁻¹) due to the solvent. In these instances, the signal which is a measure of solute absorption alone is smaller than the precision of the signal due to combined solute and solvent absorptions.
