Constmction of multilayers requires that the monolayer surface be modified to a hydroxylated one. Such surfaces can be prepared by a chemical reaction and the conversion of a nonpolar terminal group to a hydroxyl group. Examples of such reactions are the LiAlH reduction of a surface ester group (165), the hydroboration—oxidation of a terminal vinyl group (127,163), and the conversion of a surface bromide using silver chemistry (200). Once a subsequent monolayer is adsorbed on the "activated" monolayer, multilayer films may be built by repetition of this process (Fig. 8). 

One of the most common modes of characterization involves the determination of a material s surface chemistry. This is accomplished via interpretation of the fiag-mentation pattern in the static SIMS mass spectrum. This fingerprint yields a great deal of information about a sample s outer chemical nature, including the relative degree of unsaturation, the presence or absence of aromatic groups, and branching. In addition to the chemical information, the mass spectrum also provides data about any surface impurities or contaminants. 

An understanding of the surface chemistry of silica is required to interpret its chromatographic properties. The silica surface consists of a network of silanol groups, some of which may. be hydrogen bonded to water, and siloxane groups, as shown in Figure 4.2. A fully hydroxylat silica surface contains about 8... 

In taking this approach, someone new to the field of surface chemistry and catalysis can hopefully obtain a perspective on how more recent atom resolved information confirms or questions long-standing tenets. There is, therefore, a historical flavour to the book, with the first chapter dealing briefly with how did we get to where we are now . This inevitably means that the views expressed reflect personal perspectives but are very much influenced by the outstanding contributions from those who have pioneered the development of STM in surface chemistry and catalysis, of which groups at the Fritz-Haber Institut in Berlin and the universities at Aahrus, Berkeley and Stanford have been at the forefront.

In this system there is only one exothermic set of products and the problem consists of determining the vibrational distribution of the CO product in both its ground and first excited electronic states. The results can be compared with the experimental determination of Adams, Babcock, et al.,80 as well as the approximate treatment of Bates.79 Assuming some success in this endeavor, we propose to study reaction 33 to determine the HNC/HCN product ratio with potential surfaces from a French quantum chemistry group.81...
