Spatial distributions of different vibronic peaks on single naphthalocyanine molecules adsorbed on an ultrathin aluminum oxide film are imaged by a scanning tunneling microscope in real space at low temperature. The spatial variations of electron-vibronic coupling in these images reveal the interplay between the molecular comformation, the vibrational modes and the molecular orbital structure, which are in accordance with spectra recorded at different locations over the molecule.

This work shows that vibronic imaging can provide rich information of electron-vibrational coupling at the single molecule level.
