Theory and Background #

Magnesium does not exhibit any atypical properties in it’s XP spectra.

Magnesium metal exhibits strong plasmon peaks.

Experimental Advice #

Magnesium is often analysed by either the Mg 1s, or Mg 2p regions, giving easy access to very surface sensitive (Mg 1s), and deeper (Mg 2p), photoelectrons.

If using Al ka X-rays, an extended C 1s region may be helpful in correct assignment of higher energy C 1s species due to the large overlap of C 1s with Mg KLL.

Data Analysis Guidance #

Mg 2p has a very small doublet separation, to the point that it is not uncommon for analysts to use a single peak to describe the doublet state.
