Electron Magnetic Resonance of Aromatic Radicals on Metal Oxide Surfacestructure, adsorption characteristics, surface environment, and mobility of surface species often can be determined. In this review, EMR studies of radicals produced on oxide surfaces from polynuclear aromatic hydrocarbons, nitroaromatics, and sulfur-containing aromatics are considered. Intra- and in

ESR Studies of Organic Radical Cations in Zeolitesis and then to the spontaneous oxidation by activated H-exchanged zeolites of adsorped organic substrates. The nature of the oxidation site arising from thermal pretreatment in oxygen is considered, and possible mechanistic details are outlined for the frequently observed oligomerisations of simple

The interaction basically consists in the ionisation of the metal and in the stabilisation of both the released electrons and the corresponding cations at the surface. Various types of paramagnetic electron centers have been identified including surface F

Radicals on Surfaces Formed by Ionizing Radiationtion. Attention is primarily paid to ESR studies on structures and reactions of organic neutral and ionic radicals. A short introduction is also given to paramagnetic metal ions and clusters formed in zeolites and other related materials.

Photostimulated Formation of Radicals on Oxide Surfacese surfaces of oxide dielectrics (magnesium, calcium, aluminum oxides, zeolites). Three types of reactions are discussed:.On the basis of investigation of the spectral relationships and the properties of surface active centre, it is concluded that light is absorbed by coordinatively unsaturated surfa

Investigation of Radical Ions with Time-Resolved Surface Enhanced Raman Spectroscopyd electrochemically at silver or gold metal surfaces. Both single shot and pump-probe TRSERS experimental methods are illustrated which use an optical multichannel analyzer, OMA, forms (single shot) to ns (pump-probe) time resolution. Fundamental chemical and physical processes for photochemically a

ESR Studies of Organic Radical Cations in Zeolitesl cations are involved particularly in heterogeneous catalysis by zeolites, but they may well precede the formation of neutral radicals which are implicated as reaction intermediates. The reorientational dynamics of alkene radical cations in zeolites, as determined by ESR spectroscopy, are also considered.

Photostimulated Formation of Radicals on Oxide Surfacesracteristics of the photoprocesses are substantially determined by the ionization potential of solvent molecules. Mechanisms of photo- and thermostimulated processes are compared and possible similarities are discussed for all the reactions studied.
