abstract = {We have deduced the structure of the bromobenzene-$I_2$
heterodimer and the bromobenzene homodimer inside helium
droplets using a combination of laser-induced alignment,
Coulomb explosion imaging, and three-dimensional ion
imaging. The complexes were fixed in a variety of
orientations in the laboratory frame, then in each case
multiply ionized by an intense laser pulse. A three
dimensional ion imaging detector, including a Timepix3
detector allowed us to measure the correlations between
velocity vectors of different fragments and, in conjunction
with classical simulations, work backward to the initial
structure of the complex prior to explosion. For the
heterodimer, we find that the $I_2$ molecular axis
intersects the phenyl ring of the bromobenzene approximately
perpendicularly. The homodimer has a stacked parallel
structure, with the two bromine atoms pointing in opposite
directions. These results illustrate the ability of Coulomb
explosion imaging to determine the structure of large
complexes, and point the way toward real-time measurements
of bimolecular reactions inside helium droplets.},
