The Study of Adsorption on Metal Oxides by High-Resolution Electron-Energy-Loss Spectroscopy by Egdell, R

“…The technique provides a means of measuring vibrational spectra of adsorbates over a wide energy range although when dealing with non-metallic oxide substrates a strong background of intrinsic surface phonon excitations does interfere with the adsorbate loss spectra. …”

Oxygen deficiency and V and Sb doping in TiO2 and SnO2: Influences on surface electronic structure by Egdell, R

“…A shift of 0.6 eV between the vertical ionization energies in the two systems is shown to be due to the differing vibrational relaxation energies associated with very different high frequency dielectric constants for the two oxides. …”

Theory and Observations - Earth's Free Oscillations by Woodhouse, J, Deuss, A

“…Our understanding of the detailed structure of the Earth's vibrational spectrum at very long periods remains rather poor, which means that there is the likelihood that much remains to be discovered about the large-scale three-dimensional structure, that the study of very long period spectra can reveal. …”
