We report the current-voltage characteristics and inelastic electron tunneling spectra of self-assembled monolayers in a crossed-wire tunnel junction. Inelastic electron tunneling spectroscopy (IETS) enables in situ vibrational characterization of metal-molecule-metal junctions. The well defined spatial orientation of molecules in a self-assembled monolayer enables the selection rules for IETS to be explored. Results for an insulating alkane-thiol and two @pi@-conjugated molecular wires, oligo(phenylene ethynylene) and oligo(phenylene vinylene), will be presented.
