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…
Impulsive Laser Induced Alignment of Molecules Dissolved in Helium Nanodroplets
Dominik Pentlehner, Jens H. Nielsen, Alkwin Slenczka +2
We show that a 450 fs nonresonant, moderately intense, linearly polarized laser pulse can induce field-free molecular axis alignment of methyliodide molecules dissolved in a helium…
Making the best of mixed-field orientation of polar molecules: A recipe for achieving adiabatic dynamics in an electrostatic field combined with laser pulses
Jens H. Nielsen, Henrik Stapelfeldt, Jochen Küpper +3
We have experimentally and theoretically investigated the mixed-field orientation of rotational-state-selected OCS molecules and we achieve strong degrees of alignment and orientat…
Control and femtosecond time-resolved imaging of torsion in a chiral molecule
Jonas L. Hansen, Jens H. Nielsen, Christian Bruun Madsen +5
We study how the combination of long and short laser pulses, can be used to induce torsion in an axially chiral biphenyl derivative (3,5-difluoro-3',5'-dibromo-4'-cyanobiphenyl). A…
Orientation-dependent ionization yields from strong-field ionization of fixed-in-space linear and asymmetric top molecules
Jonas L. Hansen, Lotte Holmegaard, Jens H. Nielsen +3
The yield of strong-field ionization, by a linearly polarized probe pulse, is studied experimentally and theoretically, as a function of the relative orientation between the laser…
Stark-selected beam of ground-state OCS molecules characterized by revivals of impulsive alignment
Jens H. Nielsen, Paw Simesen, Christer Z. Bisgaard +5
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…
