Abstract

The singlet delta pooling rate has been measured in a chemical generator using gas phase laser Raman spectroscopy. The measured rate is four times the currently accepted pooling rate constant. Our measurement also agrees with recent ab initio rate calculations. This rate is one of the most important losses in the COIL laser and is believed responsible for the production of vibrationally excited singlet delta oxygen. The vibrationally excited oxygen is thought to play a role in the iodine dissociation process. A higher rate for this process will enhance dissociation at the cost of increased transport losses. The previous experimental measurement was reviewed and an over simplification of the data analysis identified.
