We present full quantum mechanical scattering calculations using spinning
molecules as target states for nuclear spin selective atom-diatom scattering
of reactive D+H2 and F+H2 collisions. Molecules can be forced to rotate uni-
directionally by chiral trains of short, non-resonant laser pulses, with
different nuclear spin isomers rotating in opposite directions. The
calculations we present are based on rotational wavepackets that can be
created in this manner. As our simulations show, target molecules with
opposite sense of rotation are predominantly scattered in opposite directions,
opening routes for spatially and quantum state selective scattering of close
chemical species. Moreover, two-dimensional state resolved differential cross
sections reveal detailed information about the scattering mechanisms, which
can be explained to a large degree by a classical vector model for scattering
with spinning molecules
