Excited rotational states of molecules in a superfluid
Igor N. Cherepanov, Giacomo Bighin, Constant A. Schouder +6
We combine experimental and theoretical approaches to explore excited rotational states of molecules embedded in helium nanodroplets using CS and I as examples. Laser-induc…
Gas-phase structural isomer identification by Coulomb explosion of aligned molecules
Michael Burt, Kasra Amini, Jason W. L. Lee +7
The gas-phase structures of four difluoroiodobenzene and two dihydroxybromobenzene isomers were identified by correlating the emission angles of atomic fragment ions created follow…
Alignment of the CS Dimer Embedded in Helium Droplets Induced by a Circularly Polarized Laser Pulse
James D. Pickering, Benjamin Shepperson, Lars Christiansen +1
Dimers of carbon disulfide (CS) molecules embedded in helium nanodroplets are aligned using a moderately intense, 160ps, non-resonant, circularly polarized laser pulse. It is s…
Femtosecond Laser Induced Coulomb Explosion Imaging of Aligned OCS Oligmers inside Helium Nanodroplets
James D. Pickering, Benjamin Shepperson, Lars Christiansen +1
Dimers and trimers of carbonyl sulfide (OCS) molecules embedded in helium nanodroplets are aligned by a linearly polarized 160 ps long moderately intense laser pulse and Coulomb ex…
Long-lasting field-free alignment of large molecules inside helium nanodroplets
Adam S. Chatterley, Constant Schouder, Lars Christiansen +3
Molecules with their axes sharply confined in space, available through laser-induced alignment methods, are essential for many current experiments, including ultrafast molecular im…
Switched Wave Packets with Spectrally Truncated Chirped Pulses
Adam Simon Chatterley, Evangelos Thomas Karamatskos, Constant Schouder +5
A new technique for obtaining switched wave packets using spectrally truncated chirped laser pulses is demonstrated experimentally and numerically by one-dimensional alignment of b…
Strongly aligned molecules inside helium droplets in the near-adiabatic regime
Benjamin Shepperson, Adam S. Chatterley, Anders A. Søndergaard +3
Iodine (I) molecules embedded in He nanodroplets are aligned by a 160 ps long laser pulse. The highest degree of alignment, occurring at the peak of the pulse and quantified by…
Laser-induced rotation of iodine molecules in He-nanodroplets: revivals and breaking-free
Benjamin Shepperson, Anders A. Søndergaard, Lars Christiansen +4
Rotation of molecules embedded in He nanodroplets is explored by a combination of fs laser-induced alignment experiments and angulon quasiparticle theory. We demonstrate that at lo…
Velocity map imaging with non-uniform detection: quantitative molecular axis alignment measurements via Coulomb explosion imaging
Jonathan G. Underwood, I. Procino, L. Christiansen +2
We present a method for inverting charged particle velocity map images which incoorporates a non-uniform detection function. This method is applied to the specific case of extracti…
