Abstract
The low probability of photochemical effects on XAS is in contrast to the situation with crystallography of biological specimens, where photochemical damage anywhere in the sample degrades the data set regardless of proximity to atoms of one specific element. Thermal disorder becomes important in certain types of samples and when the Debye-Waller factor is itself used as a tool. In most cases, it is more efficient to first measure room temperature spectra, and then repeat measurement using a cryostat of only those spectra where the objectives of the analysis justify an attempt to gain more information.
