Adsorption of CO on Pt(111) at 25 K and Ni(100) at 18 K has been studied
by infrared reflection absorption spectroscopy (IRAS). The occupation
ratio of terminal CO to bridged CO species on Pt(111) at 25 K ranges
from ~2.3 to 1.2 at total coverages from 0.03 to 0.13 ML, and that
of bridged CO to terminal CO species on Ni(100) at 18 K ranges from
~3.2 to 0.7 at total coverages from 0.003 to 0.15 ML. Such strong
coverage dependence of the occupation ratio, even at small coverages,
suggests that the substrate-mediated interaction between CO molecules
operates at a relatively long range (> 10 �). The isotope experiments
suggest that there is dynamic interaction between preadsorbed (accommodated)
CO species and incoming (mobile) CO species.
