ResumoThe infrared spectra of weakly bonded species from CO in contact with adsorbents containing Cr, Fe, Co and Ni were characterized as “intermedions.” The vibrational frequencies of these CO intermedions were related to the electronic energy levels of gaseous ions of these metals. From this relationship and the electronic energy levels of Ru II and Ru III, the vibrational frequencies were calculated for CO intermedions on adsorbents containing ruthenium. The infrared spectra of weakly bonded CO on adsorbents containing Ru showed bands at the calculated frequencies of 2146, 2074, and 2041 cm−1. The vibrational frequencies of species that are strongly bonded to the surface, that is, not readily removed by evacuation at room temperature are reported also.
