Dynamics of dissociation in inner-valence excited 1,3-trans-Butadiene probed by 3-D multiple ion momentum imaging

The study focuses on rapid nuclear rearrangement/isomerization taking place in an early stage of butadiene fragmentation using multiple ion momentum imaging spectroscopy and tunable synchrotron radiation. In addition, ab initio calculations are performed to disentangle the nuclear dynamics preceding dissociation.
