Analysis of Rhodium is typically performed on the Rh 3d peaks. There is a slight broadening of the 3d3/2 peak due to Coster-Kronig broadening.
Rh 3d will not overlap with C 1s features directly, however it may be beneficial to record the entire region in one sweep, to ensure appropriate background models are fit to the data, and possibly save time.
As described above, due to CK broadening, ensure peak FWHM are not locked when fitting doublets.
