The quantum yield of the potassium ferrioxalate actinometer at 365/6 mμ has been measured to be 1.26±0.03 relative to a calibrated thermopile. Comparisons of thermopiles were carried out at the Eppley Laboratory and at the National Bureau of Standards to ensure the flatness of thermopile response. Irradiations were made over the range 1012 to 3×1014 total absorbed photons.
H. H. Seliger (1964) studied this question.
