Method for normalizing and removing the solvent background. Determined XAS from 15 mM solution of (i-pr Ni), where the red solid line is the determined background by fitting the solvent path-length using a solvent model. The solvent model allows the determination of the path-length of the pure solvent (and other absorber) allowing the separation of the contributions by the solvent and by other background absorbers. The XAS from the solute only (quantity of substance in solution) was then determined by subtracting the background |
