Query: Imaging charge-migration in chiral molecules using time-resolved x-ray
  diffraction   Four-dimensional imaging of charge migration is crucial to the understanding
of several ubiquitous processes in nature. The present work focuses on imaging
of charge migration in an oriented epoxypropane: a chiral molecule. A linearly
polarized pulse is used to induce the charge migration, which is imaged by
time-resolved x-ray diffraction. It is found that the total time-resolved
diffraction signals are significantly different for both enantiomers.
Furthermore, a connection between time-resolved x-ray diffraction and the
electronic continuity equation is discussed by analyzing the time-dependent
diffraction signal and the time derivative of the total electron density in the
momentum space.
