Coo Co3o4 And Coooh David Muller Applied Physics Groupо Spectra for oxygen (o) o k edges for different cobalt oxides. the first peak is from o p co d bonded empty states, so is larger for co atoms with lower electron counts. the co formal valences are 2 , 2.667 and 3 for coo, co3o4 and coooh respectively, and the peak increases roughly with the increase in formal valence. Coo, co3o4 and coooh. co l3 and l2 edges for coo (ii), co3o4 (ii,iii), coooh (iii). the co (ii) formal valence peak is about 2 ev lower than the co (iii) peak. valence identification is best done by tracking the shift of the l3 peak, as the l3 l2 ratio is sensitive to thickness changes from plural scattering by valence excitations.
