Description: Inelastic electron tunneling in a scanning tunneling microscope (STM) provides a unique way to measure and image the excitation of an atom or molecule adsorbed on a solid surface with sub-Ångstróm resolution. Inelastic electron tunneling spectroscopy (IETS) and microscopy was first reported in 1998 for the detection of vibrational excitation in a single molecule and has since been extended to the excitation of a single electron spin and the rotation of a single molecule. This talk illustrates by three examples the use of STM-IETS to image the nature of the chemical bond in molecular structure and intermolecular interactions, spin-vibration coupling in single molecule magnetism, and single molecule vibration and dynamics in the time domain.
