title: Quick Fluorescence-EXAFS: an Improved Method for Collection of Conventional XAFS Data, an Improved Method for Collection of Conventional XAFS Data and for Studying Reaction Intermediates in Dilute Systems.
abstract: The quick EXAFS (QuEXAFS) technique provides an alternative way of recording X-ray absorption fine-structure (XAFS) data where the scan time is reduced by moving the monochromator at a constant angular speed and recording the data ;on the fly'. Results are presented to show that the use of fluorescence detection with QuEXAFS is eminently suitable for studying reactions in dilute systems such as metalloproteins at a sub-minute time scale. In addition, we show that the fluorescence-QuEXAFS technique can reduce the overall time for normal data collection by some 50% compared with conventional step-by-step scanning EXAFS using the same optical system, thus reducing the total X-ray exposures of the samples. The use of X-rays for studying in situ redox reactions is demonstrated.
