X-ray absorption tine structure

Further significant developments of the EXAFS technique are envisaged. Energy-dispersive X-ray absorption tine structure (DXAFS) allows collection of a spectrum in much less than 1 s, and its extension to the fj,s or even the ns time scale is not impossible. Polarisation-dependent total-reflection fluorescence X-ray absorption fine structure (PTRF-XAFS) permits high spatial resolution and has been applied to the copper trimer Cus on a Ti(llO) surface. The use of time-and space-resolved XAFS observation for studies of dynamic aspects of the local structure at catalyst surfaces under working conditions is forseen . Note that the acronym XAFS is used, rather than EXAFS.
