Study of fast reactions in solution using a dielectric-heating relaxation technique

Abstract

A microwave-pulse temperature-jump relaxation technique is described. Temperature rises of about 0.5 K may be produced in non-polar solvent media in about 1 µs. Spectrophotometric detection is used to monitor the resulting chemical relaxation. A conductimetric detection system is also described and applied to the measurement of relaxation times in the millisecond range in an aqueous solution.
