In tribute to the great contributions of Charlotte Moore Sitterly in critical compilations of Atomic Energy Levels, we collate some of the results from a 15-year program of atomic absorption spectroscopy of neutral species. The work reviewed has been based mainly on the utilization of the 0.5- and 2.5-GeV synchrotrons in Bonn. Such results and interpretations illustrate that no atomic structure is of the simple kind formerly associated with line series. (This applies even to the hydrogen atom, as regards Zeeman spectra.) Conversely, series can often be found in traditionally complex spectra.
