Abstract

An attempt was made to detect the photonucleation process which is outlined by Byers Brown (1995) via a detection of hydrogen peroxide as a product of this reaction. Hydrogen peroxide concentrations were found to be below the detection limit (-2 ± 2 ppb) in the case of the longest mixed gas test. The evidence of this study indicates several possibilities: either hydrogen peroxide is not the product of the photonucleation process, the CTC (charge transfer complex) has a short lifetime and therefore photonucleation is not a significant process, or photonucleation by the Byers Brown process does not occur.
