Vibrational spectroscopy has had a profound effect on our
understanding of the surface chemistry of silica. Indeed, it
has been the model system for the use of IR spectroscopy
for probing the surface chemistry of oxides, the first
studies having been carried out in late 1950. The books
written by Hair [1] and Little [2] in the sixties have
become ‘classics’ with respect to the early use of IR spec-
troscopy for studying the surface properties of silica and
adsorbed species thereon.
