Rotational coherence spectroscopy of molecules in helium nanodroplets: Reconciling the time and the frequency domains

Adam S. Chatterley, Lars Christiansen, Constant A. Schouder +7

Alignment of OCS, CS${}_2$ and I${}_2$ molecules embedded in helium nanodroplets is measured as a function of time following rotational excitation by a non-resonant, comparatively weak…
