Abstract
As we have seen already different spectroscopic and diffraction methods are best suited to studying different processes across a range of timescales. Until recently, time resolved spectroscopy was the preferred option, particularly in solution, while “snapshot” single-crystal crystallographic methods have allowed macromolecular processes to be monitored on the 100 ps timescale [1]. The latter method, of course, requires single crystals of the compound to have been grown. Another method that can be applied successfully to both solution and solid-state time-resolved measurements is EXAFS (Extended X-ray Absorption Fine Structure). EXAFS is part of the more general area of X-ray Absorption Spectroscopy (XAFS) that also includes X-ray Absorption Near Edge Structure (XANES). Thus, for a given chemical or biological system we can probe the structural dynamics over the full range of timescales form picoseconds to the metastable state (Fig. 14.1).
