In the well-known Brook rearrangment, silyl groups migrate from oxygen to carbon, but the following example is less obvious and not necessarily predictable ... [Pg.115]

In summary, the OP-term introduced by Brooks and coworkers has been transferred to a corresponding potential term in the Dirac equation. As it is demonstrated this approach allows to account for the enhancement of the spin-orbit induced orbital magnetic moments and related phenomena for ordered alloys as well as disordered. systems by a corresponding extension of the SPR-KKR-CPA method. [Pg.460]

For additional information about the x-ray emission electron-microprobe, the reader will do well to consult Birks and Brooks,11 who built a simplified probe that gave satisfactory results. They examined both metallic and nonmetallic materials, the surface of the latter being covered by evaporation with about 50 A of manganese or copper to provide sufficient electrical conductivity. Figure 9-15 illustrates an application... [Pg.264]

Data of Badder and Brooks (24). Figure 7 shows the comparisons of EPM with the experimental data obtained by Badder and Brooks (2A) in a CSTR (run C-24). The reactor feed contained 22.8% styrene, 0.64% emulsifier (sodium dodecylsulfate), and 0.39% initiator (ammonium persulfate). The residence time was 114 min. The initial reactor charge was water and emulsifier. In this case the size of the primary precursors was varied slightly from its baseline value of 1 nm to 0.8 nm. Although the experimental data show some scatter, EPM reproduces very well both the transient and steady state... [Pg.375]

The regulations covering the control of major industrial accident hazards in the United States are discussed by Brooks et al. in Lees and Ang (1989). Major hazards and their management are covered by Wells (1997). [Pg.395]

Leaving the (retro-)aldol addition-initiated threefold anionic domino processes, we are now describing sequences which are initiated by a SN-type transformation. In particular, domino reactions based on SN/1,4-Brook rearrangement/SN reactions are well known. For example, the group of Schaumann obtained functionalized cyclopentanols of type 2-461 by addition of lithiated silyldithioacetals 2-458 to epoxy-homoallyl tosylates 2-459 in 41-75% yield (Scheme 2.106) [248]. [Pg.120]

Finally, one expects spectroscopy to have an increasing impact not only on intramolecular but also on intermolecular dynamics. This includes a better understanding of the reactants, as in Figure 8.2, as well as the application of spectroscopy to the very collision process (Brooks, 1988 Neumark, 1992). At lower light intensities, spectroscopy acts in its usual role as a probe except that it is probing very transitory events. At higher intensities one can guide, not just monitor, the evolution of the system (Jortner, Levine and Pullman, 1991 Rabitz... [Pg.194]

DR. ALBERT HAIM (State University of New York at Stony Brook) I guess you know as well as I do, and as most people do, how difficult it is to find evidence for a mechanism, whether it is dissociative or associative or falls in between. You have measured volumes of activation, and have obtained information from them. You seem to be very certain as to the conclusions that you can draw from the various numbers which you obtained. Suppose that one were a little skeptical about the value of these numbers and wanted to ask how they compared with other parameters that one can measure in the same systems, such as entropies of activation, or energies of activation. From the point of view of volumes of activation, is a picture obtained which is consistent with what one may derive from other measurements ... [Pg.63]

Cindy Lee is a Professor at the Marine Sciences Research Center of Stony Brook University. Dr. Lee s research examines the distribution and behavior of biogenic organic compounds, in particular the rates and mechanisms of transformation reactions occurring as these compounds undergo alteration. Her research investigates organic compounds in the sediments and waters of open ocean and coastal areas, salt marshes, lakes, as well as the atmosphere above these areas. Her expertise centers on the analytical techniques used to measure organic matter in the ocean. Dr. Lee is cur-... [Pg.127]

In the JRS the Dalhousie Group is divided into five formations (Walker and McCutcheon 1995). Only the upper three Archibald Settlement, Sunnyside and Big Hole Brook formations (described below), are exposed in the vicinity of Nash Creek. The Archibald Settlement Formation is the lowermost of these and consists of massive flows and domes of orange to red, aphyric, commonly flow-layered rhyolite. Up section massive flows are interlayered with fine- to coarse-grained volcaniclastic rocks including heterolithic lapilli-tuff and agglomerate, as-well-as volumetrically minor feldspar-phyric rhyodacite. A U/Pb zircon age of 415.6 +/-0.4 Ma has been returned from rhyolite of... [Pg.512]

Equation (21) describes well the bond, as shown by Brooks and Gldtzel In the simplified square band model, the contribution to (21) from the f-f metallic and f-p covalent band can be written as ... [Pg.115]
