Recombination of Iodine Atoms by Flash Photolysis over a Wide Temperature Range. VII. Recombination between 206 and 300 K.

摘要

Recombination of iodine atoms was studied by flash photolysis of HI at 206 and 300 K. The photolysis produced both H and I atoms. However, under present experimental conditions, the reaction H + HI yields H2 + I was completed within the duration of the flash, thus eliminating reactive hydrogen atoms and yielding additional quantities of iodine atoms. Condensation of solid I2 on cold walls of the reaction vessel was found to be much slower than iodine recombination reaction. For these reasons I atom recombination could be studied without interference of side reactions.
