Query: A combined experimental and theoretical study on realizing and using
  laser controlled torsion of molecules   It is demonstrated that strong laser pulses can introduce torsional motion in
the axially chiral molecule 3,5-diflouro-3',5'-dibromo-biphenyl (DFDBrBPh). A
nanosecond laser pulse spatially aligns the stereogenic carbon-carbon (C-C)
bond axis allowing a perpendicularly polarized, intense femtosecond pulse to
initiate torsional motion accompanied by a rotation about the fixed axis. We
monitor the induced motion by femtosecond time-resolved Coulomb explosion
imaging. Our theoretical analysis corroborates the experimental findings and on
the basis of these results we discuss future applications of laser induced
torsion, viz., time-resolved studies of de-racemization and laser controlled
molecular junctions based on molecules with torsion.
