Multiply charged carbons from diiodoacetylene are emitted orthogonally to the laser polarization direction with significant energy, whereas those from acetylene were emitted parallel to the laser polarization direction (see scheme). The distinct carbon emissions from diiodoacetylene can be explained in terms of the persistence of a molecular frame at a high charge state, and the deformation within the Coulomb field formed by the two adjacent iodine ions.
