| Recently determined experimental and theoretical data on line strengths within 3s-3p and 3p-3d multiplets for C(I), N(II), N(I) and O(II) are analyzed. An overall satisfactory agreement between experimental data and results of recent sophisticated calculations is found with exception of only some weaker transitions. However, the measured and calculated relative line strengths disagree significantly with data resulting from the LS coupling scheme, particularly for 3p-3d transitions. In numerous cases these differences are - to a considerable degree - "regular" along the isoelectronic sequences C(I)-N(II) and N(I)-O(II). For some multiplets these discrepancies also correlate with departures from the Landé interval rule for terms involved in the corresponding transitions. |
