The temperature-jump technique is one of the most widely used methods for measuring the rates of those chemical reactions in solution which are so fast that reaction is complete as soon as the reagents are mixed. The reaction mixture is allowed to come to equilibrium, and then the equilibrium is perturbed by a rapid temperature rise, produced by Joule, microwave or laser heating. The rate at which the system adjusts to the new equilibrium is monitored by observation of the intensity of light absorbed or fluoresced, or by the electrical conductivity. Rate constants as fast as the theoretical limit of 1010 dm3 mol-1 s-1 are measurable. The review considers the limitations on the performance of temperature-jump apparatus and gives examples of systems studied.
