摘要
We provide a critical assessment of the QEXAFS (quick-scanning EXAFS) method in terms of spectral quality and resolution as a function of various experimental parameters such as scan rate, integration time, type of monochromator used, as well as an experimentally definable energy window over which a QEXAFS data point is collected. Model compounds with well-defined shape pre-edge XANES, whiteline features and long k-range EXAFS are used as test systems to arrive at a set of practical experimental parameters. The versatility, application and limitations of this time-resolved XAFS tool will be discussed.
