Quantum-state selection, alignment, and orientation of large molecules using static electric and laser fields.

Frank Filsinger, Jochen Küpper, +5 authors Henrik Stapelfeldt
The Journal of chemical physics
2009

Supersonic beams of polar molecules are deflected using inhomogeneous electric fields. The quantum-state selectivity of the deflection is used to spatially separate molecules according to their… (More)

Imaging charge transfer in iodomethane upon x-ray photoabsorption

Benjamin Erk, Rebecca Boll, +18 authors A. Mihaylovich Rudenko
Science
2014

Studies of charge transfer are often hampered by difficulties in determining the charge localization at a given time. Here, we used ultrashort x-ray free-electron laser pulses to image charge… (More)

Dynamics of neutral molecules stored in a ring

Floris M. H. Crompvoets, Hendrick L. Bethlem, Jochen Küpper, André J. A. van Roij, and Gerard Meijer Fritz-Haber-Institut der Max-Planck-Gesellschaft, Faradayweg 4-6, D-14195 Berlin, Germany;… (More)

Stark-selected beam of ground-state OCS molecules characterized by revivals of impulsive alignment.

Jens H. Nielsen, Paw Simesen, +5 authors Jochen Küpper
Physical chemistry chemical physics : PCCP
2011

We make use of an inhomogeneous electrostatic dipole field to impart a quantum-state-dependent deflection to a pulsed beam of OCS molecules, and show that those molecules residing in the absolute… (More)

Laser-induced alignment and orientation of quantum-state-selected large molecules.

Lotte Holmegaard, Jens H. Nielsen, +4 authors Gerard Meijer
Physical review letters
2009

A strong inhomogeneous static electric field is used to spatially disperse a supersonic beam of polar molecules, according to their quantum state. We show that the molecules residing in the… (More)

Two-state wave packet for strong field-free molecular orientation.

Sebastian Trippel, Terry Mullins, Nele L. M. Müller, Jens S Kienitz, Rosario González-Férez, Jochen Küpper
Physical review letters
2015

We demonstrate strong laser-field-free orientation of absolute-ground-state carbonyl sulfide molecules. The molecules are oriented by the combination of a 485-ps-long nonresonant laser pulse and a… (More)

Ultrafast charge rearrangement and nuclear dynamics upon inner-shell multiple ionization of small polyatomic molecules.

Benjamin Erk, Daniel Rolles, +25 authors A. Mihaylovich Rudenko
Physical review letters
2013

Ionization and fragmentation of methylselenol (CH(3)SeH) molecules by intense (>10(17) W/cm(2)) 5 fs x-ray pulses (ħω=2 keV) are studied by coincident ion momentum spectroscopy. We contrast the… (More)

Molecular imaging using X-ray free-electron lasers.

Anton Barty, Jochen Küpper, Henry N. Chapman
Annual review of physical chemistry
2013

The opening of hard X-ray free-electron laser facilities, such as the Linac Coherent Light Source (LCLS) at SLAC National Accelerator Laboratory in the United States, has ushered in a new era in… (More)

Photoelectron angular distributions from strong-field ionization of oriented molecules

Lotte Holmegaard, Jonas Lerche Hansen, +5 authors Lars Bojer Madsen

Imaging molecular structure through femtosecond photoelectron diffraction on aligned and oriented gas-phase molecules.

Rebecca Boll, Arnaud Rouzée, +49 authors Daniel Rolles
Faraday discussions
2014

This paper gives an account of our progress towards performing femtosecond time-resolved photoelectron diffraction on gas-phase molecules in a pump-probe setup combining optical lasers and an X-ray… (More)
