  New ab-initio surface hopping simulations of the excited state dynamics of
CS$_2$ including spin-orbit coupling are compared to new experimental
measurements using a multiphoton ionisation probe in a photoelectron
spectroscopy experiment. The calculations highlight the importance of the
triplet states even in the very early time dynamics of the dissociation process
and allow us to unravel the signatures in the experimental spectrum, linking
the observed changes to both electronic and nuclear degrees of freedom within
the molecule.
