Chemical Actinometry

The project intends to update a document published in Pure and Applied Chemistry 61, 187-210 (1989) on Chemical Actinometry. The purpose is to extend the coverage to the solid state, expand the gas phase systems and cover in more detail the near-UV radiation region, in view of the renewed interest on research in this area, due to environmental reasons. Thus, the updated document should provide a complete collection of chemical actinometers, i.e., of appropriate substances for the absolute measurement of the number of photons in a light beam exciting a sample. These measurements are required for the quantitative determination of efficiencies of photoinduced reactions. A list of recommended procedures for the most commonly used actinometers is also provided, as well as a critical discussion regarding the pros and cons of the use of chemical actinometers vs. electronic devices. Actinometers are also included for the use in biological media.

The document should be ready this summer for discussion at the IUPAC Subcommittee on Photochemistry which will meet in Budapest at the end of July on the occasion of the IUPAC Symposium on Photochemistry. A preliminary version of the document will be published in the Web sites of the three multinational photochemical associations, i.e., the Inter-American Photochemical Society (I-APS), the European Photochemical Society (EPS), and the Asia Photochemical Society (APS). Comments are welcome to this preliminary version.
