The reactor showed the transient behavior of adsorption and desorption of CO and CO_2 on magnesium oxide which was predehydrated at 350 (S_<350>) and 800℃ (S_<800.). The detailed analysis of the adsorption bands obtained demonstrated extraordinary differences in their transient behavior between S_<350> and S_<800>, and made it possible to assign many kinds of species, which were derived from the interaction of surface sites with adsorbates especially the hydroxyls, on local surface sites.}, pages = {61--79}, title = {Transient Analysis of IR Transmission Spectroscopy by Using a Spectroscopic Flow Reactor for In Situ Studie of Heterogeneous Catalysis*}, volume = {21}, year = {1989} }
