Anomalous Enhancement of the Surface Ir Modes in Photoacoustic Spectroscopy of Sio3 Particles.
J Phys Condens Matter 1989 1:5301-5304
A comparative study of the intensities of the ir modes in the photoacoustic and ftir spectroscopy of amorphous and crystalline sio2 particles is presented. It is observed that in photoacoustic spectroscopy of amorphous sio2, ir modes of surface species are enhanced by over an order of magnitude compared to the bulk ir modes of sio2. This effect, though not yet understood, may find applications in surface science.
