Title: Femtosecond nuclear motion of HCl probed by resonant x-ray Raman scattering in the Cl 1s region

Abstract

Femtosecond dynamics are observed by resonant x-ray Raman scattering (RXS) after excitation along the dissociative Cl 1s{yields}6{sigma}* resonance of gas-phase HCl. The short core-hole lifetime results in a complete breakdown of the common nondispersive behavior of soft-x-ray transitions between parallel potentials. We evidence a general phenomenon of RXS in the hard-x-ray region: a complete quenching of vibrational broadening. This opens up a unique opportunity for superhigh resolution x-ray spectroscopy beyond vibrational and lifetime limitations.

  • X-ray resonant Raman scattering (RRS) spectra of Al, Al{sub 2}O{sub 3}, Si, and SiO{sub 2} were measured at the European Synchrotron Radiation Facility, using a high-resolution Bragg-type curved crystal spectrometer. The x-ray RRS spectra were collected at several beam energies tuned below the 1s absorption thresholds of Al and Si. Differences in the spectral features between the elemental samples and the oxide ones were clearly observed. The data were interpreted using the second-order perturbation theory within the Kramers-Heisenberg (KH) approach. It is shown that, using the KH formalism, oscillator strengths that are similar to the ones deduced from x-ray absorptionmore » measurements can be extracted from emission x-ray RRS spectra. The total cross sections for the x-ray RRS process were derived for the different photon beam energies and compared with theoretical predictions. For elemental silicon, the weak 1s-3p excitation was observed and found to be consistent with results of density of states calculations.« less
  • We have studied the spectral features of Cl L{sub II,III} resonant x-ray Raman scattering of HCl molecules in gas phase both experimentally and theoretically. The theory, formulated in the intermediate-coupling scheme, takes into account the spin-orbital and molecular-field splittings in the Cl 2p shells, as well as the Coulomb interaction of the core hole with unoccupied molecular orbitals. Experiment and theory display nondispersive dissociative peaks formed by decay transitions in both molecular and dissociative regions. The molecular and atomic peaks collapse in a single narrow resonance because the dissociative potentials of core-excited and final states are parallel to each othermore » along the whole pathway of the nuclear wave packet.« less
  • Experimental and theoretical studies are reported on the inelastic (Raman) scattering of wavelength-selected polarized x rays from the K edge of gas-phase chlorine molecules. The polarized emission spectra exhibit prominent nondipole features consequent of phase variations of the incident and emitted radiation over molecular dimensions, as predicted by the Kramers-Heisenberg scattering formalism. Issues pursuant to the detection of core-hole localization by resonant Raman scattering from homonuclear diatomic molecules are critically examined. {copyright} {ital 1997 } {ital The American Physical Society}
  • The electronic structure of aqueous NH{sub 3} and ND{sub 3} has been investigated using resonant inelastic soft x-ray scattering. Spectral features of different processes involving nuclear dynamics in the core-excited state can be identified. When exciting into the lowest core-excited state, we find a strong isotope effect and clear evidence for ultrafast proton dynamics. Furthermore, a strong vibronic coupling is observed and, in the case of aqueous NH{sub 3}, a vibrational fine structure can be resolved.
  • A resonant Raman scattering study near the nitrogen-induced E{sub +} state in GaAs{sub 1-x}N{sub x} at 80 K with special emphasis on all the zone-boundary phonons is used to investigate the full symmetry of the E{sub +} state. We have observed that various phonons at the L- and X-zone boundaries not only emerge as strong and sharp Raman features for excitations near the E{sub +} transition but also exhibit the same intensity resonance enhancement as observed for the zone center phonons, longitudinal-optical ({Gamma}) and transverse-optical ({Gamma}). Our data provide strong evidence of significant L and X components in the wavemore » function of the nitrogen-induced E{sub +} state in GaAs{sub 1-x}N{sub x}.« less
