摘要：

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 measurements on a model catalyst surface are based on isotope shifts with 13CO and C18O. They are in agreement with the conclusions from infrared measurements on dispersed metal catalysts. © 1979.
