Co L23-edge photoabsorption spectra of Co compounds under various pressure conditions: (a) EY-XAS of dehydrated CoCl2 in silica gel, measured under 1 atm helium condition, (b) EY-XAS of hydrated silica gel (i.e. CoCl2·6H2O), measured under 1 atm helium/water mixture conditions, (c) EY-XAS of LiCoO2 powder, measured under high vacuum, as a standard material, and (d) spectrum from ligand-field multiplet simulation of cobalt(II) ions with D4h symmetry.  [article HTML]
