Abstract
The method of photothermal beam deflection was demonstrated for measur ing the absorption spectrum of an aqueous Nd3+ solution at temperature s between 25-degrees-C and 90-degrees-C. Changes in the magnitude of t he observed deflection can be correlated with the temperature dependen ce of both the absorptivity of the Nd3+ ions and the physical properti es of the solvent, most notably the thermo-optic coefficient dn/dT.
