Rhodium

Rh 3d5/2 binding energy values.
Rh 3d XPS spectrum of sputter cleaned rhodium metal.
Peakshape from metal standard in Figure 1 is LA(1.2,3,2). FWHMs are 0.51 eV (3d5/2) and 0.79 eV (3d3/2) at 10 eV pass energy and 0.56 eV (3d5/2) and 0.82 eV (3d3/2) at 20 eV pass energy. Note some broadening of 3d3/2 peak versus 3d5/2 peak due to Coster-Kronig effect.

Rh 3d5/2-3d3/2 splitting is 4.71 eV.
Rh 3p3/2: 497 eV
Rh 3p1/2: 512 eV
Rh 3s: 629 eV
Rh 4p: 48 eV
Rh 4s: 81 eV
