High resolution soft X-ray absorption spectroscopy for the chemical state analysis of Mn

Mn L-2,L-3 X-ray absorption spectra of various manganese compounds were mea sured using a synchrotron radiation facility. Very high-resolution spectra were obtained. Sharp lines, which were not found before, were observed, and reproducibility was checked using a different beam line in the synchrotron radiation facility. Difference in spectral line shape was observed as the difference of quantum yield method. An unknown sample was measured and the specimen was concluded to be a mixture of two different oxidation states of Mn. The effects on the change of spectral profiles are discussed.
