Ultrafast X - ray Studies of Structural Dynamics
C20 of molecular structures for C70Br10 or C60Cl24, which have been later confirmed by X-ray crystallography (partially with the use of synchrotron radiation). For the mixture of two compounds with known X-ray structures, C60Cl28 and C60Cl30, the experimental IR spectra were interpreted by comparison with the calculated ones using subtle differences for compounds possessing very similar structu...
متن کاملUltrafast Magnetization Dynamics Studies using an X-ray Streak Camera
The spin dynamics of ferromagnetic thin films following an excitation by ultrashort 100-fs near-infrared laser pulses has recently received much attention. Here, a new approach is described using x-ray magnetic circular dichroism to investigate demagnetization and magnetization switching processes. In contrast to magneto-optical measurements, x-ray dichroism has the advantage of determining sep...

متن کاملX-ray structural studies of some metalloproteins
Metalloproteins are an important class of proteins and perform a variety of biological processes. They are ideally suited for Synchrotron Radiation studies. In particular, X-ray region of the spectrum has been very effectively exploited not only for crystallographic structure determinations but X-ray absorption fine structure (XAFS) and more recently X-ray solution scattering techniques have al...
متن کاملUltrafast structural changes measured by time-resolved X-ray diffraction
High-intensity X-ray pulses from third-generation synchrotron sources make it possible to study the temporal dynamics of rapidly evolving materials. We report a study of rapid and reversible disordering of the structure of an InSb crystal induced by an ultrashort laser pulse. A novel crosscorrelation detection technique is described, which allowed us to observe rapid changes in X-ray diffractio...
