A single-crystal microspectrophotometer has been implemented on SRS beamline 10.1 providing a unique facility for combined crystallographic with on-line XAS-optical spectroscopic measurements from the same crystal. The need for such an approach is highlighted by data showing the rapid X-ray photoreduction of type-1 Cu centres.

Methods for classifying Fe-bearing minerals according to features of their Fe K-edge XANES spectra are presented. These spectra are abstracted into two-dimensional plots in which various types of species, such as divalent or trivalent Fe oxides, fall into distinct regions.

A solution of the problem of dynamical diffraction for X-ray pulses with arbitrary dimensions in the Bragg and Laue cases in a crystal of any thickness and asymmetry coefficient of reflection is presented. Analysis of pulse form and duration transformation in the process of diffraction and propagation in a vacuum is conducted. It is shown that only the symmetrical Bragg case can be used to avoid smearing of reflected pulses.
