Research Abstract

A novel method for the contactless measurements of charge migration was applied to π-conjugated molecules in each of which a bromine atom and an oxygen atom are located on the opposite sides of the aromatic ring. A core hole was generated selectively in the Br atom by X-ray absorption, followed by the Auger cascade, and the subsequent charge migration within the molecule was examined by detecting an O^+ ion by means of the coincidence momentum imaging measurements.
