Ultrafast scattering using X-rays or electrons is an emerging method to obtain structure dynamics at the atomic length and time scales. However, directly resolving in real-space atomic motions is inherently limited by the finite detector range and the probe energy. As a result, the time-resolved signal interpretation is mostly done in reciprocal space and relies on modeling and simulations of specific structures and processes. Here, we introduce a model-free approach to directly resolve…

Resolving multiphoton processes with high-order anisotropy ultrafast X-ray scattering.

We present the first results on experimentally measured ultrafast X-ray scattering of strongly driven molecular iodine and analysis of high-order anisotropic components of the scattering signal. We

Molecular dynamics is now routinely studied on femtosecond time scales using various spectroscopies. However, direct structural information of all nuclear coordinates involved in such dynamical

Theory of ultrafast x-ray scattering by molecules in the gas phase.

A new, detailed, and fully converged simulation of ultrafast total x-ray scattering by excited H2 molecules illustrates the theory and demonstrates that the inelastic component can contribute strongly to the total difference scattering signal, i.e., on the same order of magnitude as the elastic component.

Characterizing Multiphoton Excitation Using Time-Resolved X-ray Scattering

Molecular iodine was photoexcited by a strong 800 nm laser, driving several channels of multiphoton excitation. The motion following photoexcitation was probed using time-resolved X-ray scattering,

We describe, within the framework of quantum electrodynamics, an interaction between a non-resonant hard x-ray pulse and an electronic system in the presence of a temporally periodic laser field

Imaging Molecular Motion: Femtosecond X-Ray Scattering of an Electrocyclic Chemical Reaction.

By mapping nuclear motions using femtosecond x-ray pulses, this work has created real-space representations of the evolving dynamics during a well-known chemical reaction and shown a series of time-sorted structural snapshots produced by ultrafast time-resolved hard x-rays.
