The scanning tunneling microscope (STM) allows great control over atomic and molecular manipulation on surfaces. The microscope tip can also be used to record vibrational spectra that allow the identification and characterization of single adsorbed molecules and the bonds they form with the substrate. Lee and Ho (p. 1719) used these combined capabilities of their low-temperature STM to study the bond formation between single iron atoms on a silver surface and carbon monoxide (CO) molecules delivered with the STM tip. Complexes of iron with one or two CO molecules were formed and characterized.
