Photoelectron spectroscopy, bioinorganic

Cu(I) d10 It is instructive to first consider a reduced Cu site that has a filled subshell d10 electron configuration. This cannot be studied by most of the spectroscopic methods used in inorganic and bioinorganic chemistry (the alternative approach is photoelectron spectroscopy (PES) that is presented in Ref. 45). The edge for a Cu(I) complex is at 8990 eV and corresponds to the threshold energy for... 

The following section includes discussion of several applications of photoelectron spectroscopy to the study of bioinorganic model complexes. The Further Reading section at the end of this article lists previous reviews and articles and other applications in inorganic and organometallic chemistry that can be consulted for areas not covered here. 

X-ray photoelectron (XPS-ESCA) spectroscopy uses inner-shell electron transitions to determine the oxidation state of metals in bioinorganic species.
