Abstract
We examine x-ray scattering from an isolated organic molecule from the linear to nonlinear absorptiveregime. In the nonlinear regime, we explore the importance of both the elastic and inelastic channelsand observe the onset of nonlinear behavior as a function of pulse duration and energy. In the linearregime, we test the sensitivity of the scattering signal to molecular bonding and electronic correlationvia calculations using the independent atom model (IAM), Hartree-Fock (HF) and density functionaltheory (DFT). Finally, we describe how coherent x-ray scattering can be used to directly visualizefemtosecond charge transfer and dissociation within a single molecule undergoing x-ray multiphotonabsorption.
