Impact of dissociation and ionization on properties of iodine vapor
- Department of Aerospace Engineering, University of Southern California, Los Angeles, California 90089-1191 (United States)
The partition functions are calculated for the [sup 127]I[sup 127]I iodine molecule, the [sup 127]I atom, and the corresponding singly charged atomic ion and are subsequently used in calculating the dissociation and ionization degrees as well as the thermodynamic functions in iodine vapor in local thermal equilibrium in the temperature range of 700[le][ital T][le]12 000 K. It was found that at densities greater than 10[sup 14] cm[sup [minus]3] iodine dissociates at rather low temperatures ([ital T][lt]3000 K) and only achieves significant ionization at high temperatures ([ital T][gt]10 000 K). This makes iodine a convenient model gas for studying chemical nonequilibrium in diatomic gases.
