Abstract: We study ultrafast charge rearrangement in dissociating 2-iodopropane $(2\text{\ensuremath{-}}{\mathrm{C}}_{3}{\mathrm{H}}_{7}\mathrm{I})$ using site-selective core ionization at the iodine atom. Clear signatures of electron transfer between the neutral propyl fragment and multiply charged iodine ions are observed in the recorded delay-dependent ion momentum distributions. The detected charge-transfer pathway is only favorable within a small (few angstroms), charge-state-dependent spatial window located at C-I distances longer than that of the neutral ground-state molecule. These results offer insights into the physics underpinning charge transfer in isolated molecules and pave the way for a different class of time-resolved studies.
