“…T he m agnetic bottle m ultielectron coincidence spectrom eter, described in Ref. [4] was used at the PLEIA DES beam line [19][20][21][22][23], w hich has two undulators H U 256 and H U 80 covering the 7 -1 0 0 0 eV energy range. T he photon resolution was set at 65, 70, and 110 meV for the photon energies used to collect those data sets (175, 185, and 250 eV, respectively).…”

Single and double Auger processes following ionization of 4 / and 5p inner shells have been studied using multielectron coincidence spectroscopy. Coincidence technique enables us to resolve state by state all single and double Auger paths with a resolution better than the lifetime broadening. Drastic step-to-step decay lifetime changes are observed and reported as Coster-Kronig transition takes place either in the first (5p) or in the second ( 4 /) step of the Auger cascade. Relativistic ab initio theory has been used to predict and interpret the experimental observations.

“…The new measurements have been carried out at the PLEIADES beamline (10-1000 eV) dedicated to ultrahigh resolution spectroscopic studies of isolated species [33][34][35][36] at the 2.75 GeV French national synchrotron radiation laboratory SOLEIL. The quasiperiodic Apple II elliptical undulator of 80 mm period (HU80) has been used to generate arbitrarily tilted linearly polarized light.…”

Current techniques based on x-ray or electron diffraction are successfully employed for structure determination in condensed matter but are sometimes limited when applied to low density media such as the gas phase. Here we show that vibrationally resolved photoelectron spectroscopy based on x rays generated by third generation synchrotron light sources can be used to infer the structure of isolated molecules in a simple and efficient way. In particular, we show that vibrational ratios obtained from inner shell C 1s photoelectron spectroscopy of isolated methane molecules exhibit pronounced oscillations that are the fingerprints of electron diffraction by the surrounding atomic centers, thus providing the necessary information for the determination of the molecular geometry.

“…The latter allow one to keep the monochromator diffraction efficiency optimal for arbitrarily chosen photon energies within the operating range. 30 For the present experiment, 400 lines mm −1 (at C and N edges) and 1600 lines mm −1 (at the O edge) gratings were used, which provide high photon flux on the order of (1−2) × 10 12 photons s −1 /0.1% bandwidth in the used energy range. 31 Multiply protonated cytochrome c from equine heart (Sigma Aldrich) molecules was generated by the ESI source from a water/acetonitrile (75:25) solution at 10 μM.…”

C, N, and O near-edge ion yield spectroscopy of 8+ selected electrosprayed cations of cytochrome c protein (12 kDa) has been performed by coupling a linear quadrupole ion trap with a soft X-ray beamline. The photoactivation tandem mass spectra were recorded as a function of the photon energy. Photoionization of the precursor, accompanied by CO2 loss, is the dominant relaxation process, showing high photoion stability following direct or resonant photoionization. The partial ion yields extracted from recorded mass spectra show significantly different behaviors for single and double ionization channels, which can be qualitatively explained by different Auger decay mechanisms. However, the single ionization spectra reveal characteristic structures when compared to existing near-edge X-ray absorption fine structure (NEXAFS) spectra from thin films of peptides and proteins. Therefore, the present experiment opens up new avenues for near-edge X-ray spectroscopy of macromolecules in the gas phase, overcoming the radiation damage issue or the environmental effects as due to the surface, intermolecular interactions, and solvent.
