Nickel K- and L-edge X-ray absorption spectra (XAS) are discussed for 16 complexes and complex ions with nickel centers spanning a range of formal oxidation states from II to IV. K-edge XAS alone is shown to be an ambiguous metric of physical oxidation state for these Ni complexes. Meanwhile, L-edge XAS reveals that the physical d-counts of the formally Ni compounds measured lie well above the d count implied by the oxidation state formalism.

Article Synopsis
- The study investigates the electrochemical behavior of the anthracene-based azo dye azo-OMe, focusing on how its reduction potential varies with different organic acids and their pH levels.
- The analysis reveals that for organic acids with a pH between 8 and 20, the reduction potential of azo-OMe depends significantly on the acid's pH.
- Kinetic studies, including isotope effects, demonstrate that the reactions are limited by diffusion and that a simultaneous transfer of protons and electrons occurs during the reduction process, particularly with trifluoroacetic acid.
