Abstract
Theoretical f values are reported for the 1657 and 1329 Å transitions of carbon I and the 485, 549, 457, and 513 Å transitions of fluorine II. These involve excited states not lowest of their symmetry. We calculate these using the nonclosed shell many electron theory (NCMET) of Sinanoğlu and proper application of the variational theory required for such nonlowest of symmetry states. The results of this work differ from Hartree–Fock and other values in previous literature by factors of 2–5. Experimental values, where available, are in good agreement with the results of this work. New experimental measurements by methods such as beam foil spectroscopy are recommended for several transitions.
