H in control (of the electrons) : The bond strength of CO on small cationic cobalt clusters, as indicated by the CO stretching band in the IR spectrum, can be precisely controlled by coadsorption of H 2 molecules. Each coadsorbed H atom reduces the electron density available for back‐donation by about 0.09–0.25 electrons, depending on cluster size.
