So your goal is to plot If/I0 versus time for a given energy in the XANES. Are you exporting normalised XANES or just If/I0? Are you doing background removal from the pre-edge?
Is another feature underlying this targeted feature also disappearing or changing? i.e. you are not watching a feature increase from zero but instead changing from one to another? ...or seeing a background increase as well? Was the fluorescence measured using a solid state detector? Did the deadtime of the detector increase significantly as the signal from the sample increased (and no deadtime correction applied) ? -R.
