Chemical Actinometry
(IUPAC Technical Report)


H.J. Kuhn, S.E. Braslavsky, and R. Schmidt
Pure and Applied Chemistry
Vol. 76, No. 12, pp. 2105-2146 (2004)

This document updates the first version of the IUPAC technical report on “Chemical Actinometers” published in Pure and Applied Chemistry, 61, 187–210 (1989). Since then, some methods have been improved, procedures have been modified, and new substances have been proposed as chemical actinometers. An actinometer is a chemical system or a physical device by which the number of photons in a beam absorbed into the defined space of a chemical reactor can be determined integrally or per time. This compilation includes chemical actinometers for the gas, solid, microheterogeneous, and liquid phases, as well as for use with pulsed lasers for the measurement of transient absorbances, including the quantum yield of phototransformation. The literature for each of the actinometers is included as well. The actinometers listed are for use in the wavelength range from UV to the red region of the spectrum. A set of recommended standard procedures is also given. Advantages and disadvantages are discussed regarding the use of chemical actinometers vs. electronic devices for the measurement of the number of photons absorbed. Procedures for the absolute measurement of incident photon flux by means of photodiodes are also discussed.
