Researchers Part Water: ‘Electric Prism’ Separates Water’s Nuclear Spin States

05 September 2014

Using an "electric prism", scientists have found a new way of separating water molecules that differ only in their nuclear spin states and, under normal conditions, do not part ways.

Watching electrons jump in exploding molecules

17 July 2014

Our results on charge transfer in dissociating iodomethane (CH3I) molecules by Erk, Boll, Trippel, et al has been published by Science. In this study, the maximum distance at which electrons can still transfer between the ionized iodine and methyl moieties of the dissociating molecule was measured. Detailed press releases are available from DESY, CUI, and SLAC.

Skinner prize for the best student poster

10 July 2014

The Skinner prize at the Faraday Discussions 171 "Emerging Photon Technologies for Chemical Dynamics" was awarded, jointly, to Rebecca Boll (DESY FS-FL) and Thomas Kierspel (DESY FS-CFEL-1/CMI) for their posters on photoelectron holography and on state and conformer selection. The latter showed the spatial separation of the cis and trans isomer of 3-fluorophenol, fragmentation studies of indole and indole-water clusters, and a discussion on the possibility to separate different conformers of glycine. Congratulations to Rebecca and Thomas!

New publication on quantum pendulum in the Physical Review A

30 May 2014

Our work on the pendular wave packet dynamics of state selected OCS, entitled “Strongly driven quantum pendulum of the OCS molecule”, has been published in Physical Review A 89, 051401(R) (2014) and has been selected as Editors' Suggestion. We present a combined experimental and theoretical study of molecular alignment in the intermediate pulse-duration regime including a comparison to experiments in the impulsive and adiabatic limits. A molecular movie illustrates this motion.

Gas-phase diffraction published in Phys. Rev. Lett.

28 February 2014

Our paper about the first experimental demonstration of x-ray diffraction from ensembles of quantum-state selected and laser-aligned gas-phase molecules, performed at the X-ray Free-Electron Laser LCLS is published: "X-Ray Diffraction from Isolated and Strongly Aligned Gas-Phase Molecules with a Free-Electron Laser", Phys. Rev. Lett. 112, 083002 (2014). This experiment is a first step toward coherent diffractive imaging of structures and structural dynamics of isolated molecules at atomic (picometers and femtoseconds) resolution in future experiments at X-ray free-electron lasers. The work is covered by a press releases and an APS Focus story.
