ENERGY LEVELS, PARTITION FUNCTIONS AND FRACTIONAL ELECTRONIC POPULATIONS FOR NITROGEN AND OXYGEN ATOMS AS TO 25,000 DEGREES K,

Energy levels for N, N, N2, N3, O, O, O2, and O3 are tabulated for all possible electronic states or groups of states having two electrons in the n 1 shell, one electron in the n 2 to 8 shell, and the remaining electrons in the n 2 shell. Where experimental values were not availale, theoretical estimates were made. The corresponding partition functions and frac tional populations for each electronic state of these species were calculated on an IBM 7090 and are reported for 34 temperatures between 1000 and 25,000 K. Alternate partition functions includ ing only electronic states out to n 4 are also tabulated. Author
