Abstract

The vast majority of infrared spectrometry of surface species is currently performed using the same type of sampling technique described by Eischens et al. in 1956, in which the transmittance of a very thin disk of the adsorbent is measured. Although a wealth of data on surface species has been obtained in this way, the transmittance of the samples is quite low across the spectrum, especially at very high wavenumber (where scattering is greatest) and at low wavenumber (where most adsorbents exhibit strong absorption bands). Other techniques which have been studied include reflection-absorption (R-A) spectrometry, for which only very weak bands due to adsorbed species at monolayer or partial monolayer coverage can be observed, and emission spectrometry, which is plagued by severe emission from the adsorbent and the effect of temperature gradients.
