How carbon monoxide bonds to alumina-supported rhodium particles: tunneling spectroscopy measurement with isotopes. Technical report

Carbon monoxide chemisorbs in at least three different ways on alumina-supported rhodium particles: There are two different linear-bonded species and at least one bridge-bonded species. These conclusions from tunneling measurement on a model catalyst surface are based on isotope shifts with CO13 and C(18)O. They are in agreement with the conclusions from infrared measurements on dispersed metal catalysts.
