Time-Resolved Molecular Frame Dynamics of Fixed-in-Space CS2 Molecules
Random orientation of molecules within a sample leads to blurred observationsof chemical reactions studied from the laboratory perspective. Methodsdeveloped for the dynamic imaging of molecular structures and processesstruggle with this, as measurements are optimally made in the molecular frame.Here we uselaser alignment to transiently fix CS2 molecules in space longenough to elucidate, in the molecular reference frame, details of ultrafast electronic vibrationaldynamics during a photochemical reaction. These three-dimensional photoelectron imaging results, combined with ongoing efforts in molecular alignment and orientation, presage a wide range of insights obtainable fromtime-resolved studies in the molecular frame.
