Abstract
  
Time-resolved laser spectroscopy and established x-ray methods have recently been
combined to probe the local electronic피망 바카라and피망 바카라molecular피망 바카라structure피망 바카라with피망 바카라femtosecond
x-ray pulses in time and energy. In the피망 바카라soft x-ray피망 바카라range,피망 바카라core-level피망 바카라transition피망 바카라are
particularly sensitive to valence-charge distributions and to chemical coordination of

holding tremendous potential for following chemical bonding and the formation of new
molecular species in real time. This is particularly powerful for understanding molecular
dynamics in solution, where important chemistry occurs. We study the피망 바카라ultrafast피망 바카라spin
