Resonant inelastic x-ray scattering on iso-C2H2Cl2 around the chlorine K-edge : Structural and dynamical aspects

• We report a theoretical and experimental study of the high resolution resonant K-alpha X-ray emission lines around the chlorine K-edge in gas phase 1,1-dichloroethylene. With the help of ab initio electronic structure calculations and cross section evaluation, we interpret the lowest lying peak in the X-ray absorption and emission spectra. The behavior of the K-alpha emission lines with respect to frequency detuning highlights the existence of femtosecond nuclear dynamics on the dissociative Potential Energy Surface of the first K-shell core-excited state.
