Figure 7
(a) Pd K-edge XAS measured on a Pd metallic foil; spectra are collected at a rate of 1 Hz. The cam is moved through successive steps to change the oscillation amplitude during the measurement. The time required to change a cam amplitude of 1° is 1 s and the transition from one amplitude to another is virtually invisible (first spectra at the top, last at the bottom). (b) Enlarged view of XANES spectra and (c) their first derivatives. Spectra have not been realigned or smoothed but simply averaged between successive cam changes to obtain a better signal to noise on the first derivative.
