摘要: Abstract Infrared spectra of CO adsorbed on Pt{111} indicate only one linear and bridging species below θ = 0.5. The band is subject to a positive dipole-coupling shift negative chemical one, both which exhibit maximum when plotted as function coverage. When q > 0.50, complex temperature-dependent pattern shifts splittings arises in bands. behaviour the reported an earlier paper by Hayden Bradshaw was not observed. In addition bands characteristic perfect surface, second band, about 15 cm−1 first, produced defect sites: we show that such defects are likely have very significant effects studies Pt{111}-CO system. We also propose real-space interpretation low-coverage LEED patterns first Steininger et al.
