Laser Photoreactions of Volatile Surface-Adsorbed Molecules
Adsorbed layers, which form on solid surfaces exposed to molecular vapors, represent complex inhomogeneous phases. Modern studies of the diverse molecule-surface and intermolecular chemical interactions in these systems have been weighted heavily toward single monolayers, and specifically toward tightly chemisorbed monolayer systems or systems at cryogenic temperatures, in order to make use of surface diagnostics such as Auger spectroscopy and electron diffraction [1f. Chemically passive and immobile systems have been chosen because of the relatively long measurement times and the ultrahigh-vacuum requirements of these surface diagnostics.
