Fluorescence spectroscopy is an important analytical technique with many applications in e.g. physics and medicine. To use it as a genuinely versatile tool we need a detailed knowledge of the fluorescence spectra, and inner-shell atomic physics in general. In the last four decades the inner-shell dynamics of atoms has been studied using of photoabsorption, photoion and photoelectron spectroscopy. Additional information at high resolution can be obtained from fluorescence spectroscopy. Recently the fluorescence yields upon 1s ionisation of neon (by an indirect method), 2p excitation of argon, and 1s excitation of molecular nitrogen, have been measured and interpreted.
