%X <p>The method of photothermal beam deflection was demonstrated for measuring the absorption spectrum of an aqueous Nd<sup>3+</sup> solution at temperatures between 25°C and 90°C. Changes in the magnitude of the observed deflection can be correlated with the temperature dependence of both the absorptivity of the Nd<sup>3+</sup> ions and the physical properties of the solvent, most notably the thermo-optic coefficient d<em>n</em>/d<em>T</em>.</p>
