Vinícius Vaz, Da Cruz. Anomalous polarization dependence in vibrationally resolved resonant inelastic x-ray scattering of H2O [Текст] / Da Cruz Vinícius Vaz, Ertan Emelie, Ignatova Nina, Rafael C.

It is well established that different electronic channels, in resonant inelastic x-ray scattering (RIXS), display
different polarization dependences due to different orientations of their corresponding transition dipole moments
in the molecular frame. However, this effect does not influence the vibrational progression in the Franck-Condon
approximation. We have found that the transition dipole moments of core excitation and deexcitation experience
ultrafast rotation during dissociation in the intermediate core-excited state. This rotation makes the vibrational
progression in RIXS sensitive to the polarization of the x-ray photons.We study the water molecule, in which the
effect is expressed in RIXS through the dissociative core-excited state where the vibrational scattering anisotropy
is accompanied also by violation of parity selection rules for the vibrations.
