Spatially separated polar samples of the cis and trans conformers of 3-fluorophenol
Thomas Kierspel, Daniel A. Horke, Yuan-Pin Chang +1
We demonstrate the spatial separation of the cis- and trans-conformers of 3-fluorophenol in the gas phase based on their distinct electric dipole moments. For both conformers we cr…
CMISTARK: Python package for the Stark-effect calculation and symmetry classification of linear, symmetric and asymmetric top wavefunctions in dc electric fields
Yuan-Pin Chang, Frank Filsinger, Boris G. Sartakov +1
The Controlled Molecule Imaging group (CMI) at the Center for Free Electron Laser Science (CFEL) has developed the CMIstark software to calculate, view, and analyze the energy leve…
Specific chemical reactivities of spatially separated 3-aminophenol conformers with cold Ca ions
Yuan-Pin Chang, Karol Długołęcki, Jochen Küpper +3
Many molecules exhibit multiple rotational isomers (conformers) that interconvert thermally and are difficult to isolate. Consequently, a precise characterization of their role in…
Mixed-field orientation of molecules without rotational symmetry
Jonas L. Hansen, Juan J. Omiste, Jens H. Nielsen +4
The mixed-field orientation of an asymmetric-rotor molecule with its permanent dipole moment non-parallel to the principal axes of polarizability is investigated experimentally and…
X-ray diffraction from isolated and strongly aligned gas-phase molecules with a free-electron laser
Jochen Küpper, Stephan Stern, Lotte Holmegaard +52
We report experimental results on x-ray diffraction of quantum-state-selected and strongly aligned ensembles of the prototypical asymmetric rotor molecule 2,5-diiodobenzonitrile us…
Strongly aligned and oriented molecular samples at a kHz repetition rate
Sebastian Trippel, Terry Mullins, Nele L. M. Müller +3
We demonstrate strong adiabatic laser alignment and mixed-field orientation at kHz repetition rates. We observe degrees of alignment as large as cosΘ=0.94 at 1 kHz operation for io…
