X-ray fluorescence spectroscopy XFS

Other analytical techniques that have been employed for measuring barium and its compounds in environmental media include x-ray fluorescence spectroscopy (XFS), neutron activation analysis (NAA), scintillation spectroscopy, and spectrography (Boothe and James 1985 Landis and Coons 1954 Larsen 1973 Murata and Noguchi 1974 Oppenheimer et al. 1984). XFS and NAA methods are less sensitive than other available analytical methods for measuring barium or its compounds in environmental media. Scintillation spectroscopy and spectrography are less commonly used to measure barium in the environment relative to other analytical methods.

Any variations in the composition, structure, stereochemistry or coordination character of a molecule change its chemical properties and MO (molecular orbital) structure. MO changes are clearly observed by the fine structure of XFS (X-ray fluorescence spectroscopy). This makes it possible to relate some features of the chemical behaviour of compounds to their electronic structure and opens a way to various chemical property-electronic structure parameter correlations which are frequently of help for explaining and predicting the chemical properties of compounds.
