Analysis of the Spectrum of Doubly Ionized Molybdenum (Mo III).
The spectrum of doubly ionized molybdenum (Mo III) was produced in a sliding spark discharge and recorded photographically on the NIST 10.7-m normal incidence spectrograph in the 800-3250 Å spectral region. The analysis has led to the establishment of 76 levels of the interacting 4d4, 4d35sand 4d25s2even configurations, 73 levels of the interacting 4d35dand 4d36seven configurations, and 181 levels of the interacting 4d35pand 4d25s5podd configurations. Approximately 3100 lines have been classified as transitions between these experimentally determined levels. Comparison between the observed levels and those calculated from matrix diagonalizations with least-squares fitted parameters shows standard deviations of 44, 33, and 183 cm-1, respectively, for the levels of the three sets of configurations.
