Raman spectroscsopy is used for studying molecular transport junctions (MTJs), but it cannot distinguish molecules participating in electrical transport from nearby inactive molecules. Here, on‐wire lithography‐generated nanostructures are used to study MTJs through inelastic electron tunneling spectroscopy complemented by Raman spectroscopy to fingerprint the molecules participating in electrical conduction, while observation of host‐guest interactions confirms their functionality.
