| Abstract: | Abstract— A semi-rigorous treatment for errors involved in correcting absorbed light intensities based on measurement of transmitted intensities is given. Several common systems are discussed: vapour system with a vapour actinometer, vapour system with a liquid actinometer, and liquid system with a liquid actinometer. In each case, correction factors have been calculated, which can be conveniently applied to the majority of quantitative photochemical systems. In addition, a treatment is given for the case where a separate cell containing the actinometer is used in place of a photodiode. |
