▪ Abstract Molecular structures during chemical processes are crucial for predicting
molecular reactivity and reaction mechanisms. Using a laser pulse as an internal clock for …

In conventional ferroelectrics the polarization is induced either by the relative displacement
of positive and negative ions due to a lattice distortion or by the collective alignment of …

Theoretical progress in the research of photoinduced phase transitions is reviewed with
closely related experiments. After a brief introduction of stochastic evolution in statistical …

Photoinduced transitions from ionic (I) to neutral (N) and neutral (N) to ionic (I) phases in an
organic charge transfer (CT) complex, tetrathiafulvalene-p-chloranil (TTF-CA), were …

X-ray diffraction with femtosecond time-resolution represents a direct probe of ultrafast
structural changes in condensed matter. The generation of ultrashort X-ray pulses in laser …

We report the spin state photo-switching dynamics in two polymorphs of a spin-crossover
molecular complex triggered by a femtosecond laser flash, as determined by combining …

NW14A is a newly constructed undulator beamline for 100 ps time-resolved X-ray
experiments at the Photon Factory Advanced Ring. This beamline was designed to conduct …

Fast and ultra-fast time-resolved diffraction is a fantastic tool for directly observing the
structural dynamics of a material rearrangement during the transformation induced by an …

Experimental and computational methods for time-resolved (TR) diffraction now allow the
determination of geometry changes on molecular excitation. The first results indicate …

Spin-crossover (SCO) materials exhibit thermal conversion of their electronic state from low
(LS) to high (HS) spin state, which also involves both intra-and inter-molecular structural …
