Photophysical measuring techniques for the study of gas/liquid reactors . After a brief account of the fundamentals of photophysics, the authors describe various photophysical measuring procedures, with reference to available instrumentation, including prices. The measuring methods permit contactless and intertialess determination of various quantities in very small volumes (temperature, viscosity, concentration, pH, orientation of molecules, etc.). The authors examine which methods are available for the study of gas/liquid reactors. The most promising studies seem to involve the heat effects accompanying absorption with chemical reaction, study of interfacial effects (slowing mass transfer by accumulation of surface‐active impurities, Marangoni effect), and the observation of complex reaction systems. Photophysical measuring techniques can also be used for measurements in industrial reactors; some of the known applications are described.
