Capturing molecular structural dynamics by 100 ps time-resolved X-ray absorption spectroscopy
نویسندگان
چکیده
An experimental set-up for time-resolved X-ray absorption spectroscopy with 100 ps time resolution at beamline NW14A at the Photon Factory Advanced Ring is presented. The X-ray positional active feedback to crystals in a monochromator combined with a figure-of-merit scan of the laser beam position has been utilized as an essential tool to stabilize the spatial overlap of the X-ray and laser beams at the sample position. As a typical example, a time-resolved XAFS measurement of a photo-induced spin crossover reaction of the tris(1,10-phenanthrorine)iron(II) complex in water is presented.

Direct observation of myoglobin structural dynamics from 100 picoseconds to 1 microsecond with picosecond X-ray solution scatteringwz
Myoglobin (Mb) is a heme protein that carries small-molecule ligands such as O2, CO and NO in muscles, and can be considered as a subunit of hemoglobin, a paradigm protein for the study of allostery. Due to its small size, availability and photosensitivity of the heme–ligand bond, Mb has served as a prototypical model system for studying protein structural dynamics. Accordingly, structural dyna...

We explore the InSb-semiconductor lattice dynamics after excitation of high density electron-hole plasma with an ultrashort and intense laser pulse. By using time resolved x-ray diffraction, a sub-mÅ and sub-ps resolution was achieved. Thus, a strain of 4% was measured in a 3 nm thin surface layer 2 ps after excitation. The lattice strain was observed for the first 5 ps as exponentially decayin...

In this study, we perform steady-state and time-resolved X-ray absorption spectroscopy (XAS) on the iron K-edge of [Fe(tren(py)3)](PF6)2 dissolved in acetonitrile solution. Static XAS measurements on the low-spin parent compound and its high-spin analogue, [Fe(tren(6-Me-py)3)](PF6)2, reveal distinct spectroscopic signatures for the two spin states in the X-ray absorption near-edge structure (XA...

A time-resolved x-ray absorption study of the structural dynamics of liquid water on a picosecond time scale is presented. We apply femtosecond mid-infrared pulses to resonantly excite the intramolecular O-H stretching band of liquid water and monitor the transient response in the oxygen K-edge absorption spectrum with picosecond x-ray pulses. In this way, structural changes in the hydrogen bon...

The charge-carrier dynamics of anatase TiO2 nanoparticles in an aqueous solution were studied by femtosecond time-resolved X-ray absorption spectroscopy using an X-ray free electron laser in combination with a synchronized ultraviolet femtosecond laser (268 nm). Using an arrival time monitor for the X-ray pulses, we obtained a temporal resolution of 170 fs. The transient X-ray absorption spectr...
