The relations 4- > 2-position in rate and 4- < 2-position in will apparently apply to reactions with anions, but the reverse relation is observed in piperidination, presumably due to 2-substitution being favored by hydrogen bonding in the zwitterionic transition state (cf. 47, 59, and 277) or by solvent-assisted proton removal from the intermediate complex (235). Substitutions of polychloroquino-lines (in which there is a combined effect of azine-nitrogen and unequal mutual activation of the chlorine substituents) also show 4- > 2-position in reactivity contrary statements are documented by these same references. Examples are cited below of the relation 2- > 4-position when a protonated substrate or a cyclic transition state is involved. [Pg.364]

The two following examples are different with respect to the demands, constraints, objective functions and the whole master data and transaction data. They were constructed as reference examples out of real life requirements and real life systems. [Pg.68]

The above example was used as a reference example in the European Research Proj ect AM ETI ST [46]. A comparison with other solution approaches clearly showed the advantage of the quant-based combinatorial optimization. [Pg.75]

Tunnelling of a single particle in a symmetric double minimum potential is also a reference example of quantum interference for neutron scattering. Even if there is no such symmetrical double minimum potential for KHCO% [Fil-laux 1983 (b)], this case deserves particular attention for further comparison with Eq. (20). [Pg.522]

Case 1 b = RT/pF with p = constant = 0.5 - the classical expression for b with conventional T-dependence. (For this case, should be recovered without complications. This is just a reference example). [Pg.170]

Atomic force microscope tips can also be used to deposit matter on a surface at nanometer scale. The reference example is dip-pen nanolithography where molecules deposited on the tip diffuse to the surface when in contact and define patterns with dimensions as small as 15 nm. An extension is the so-called NADIS technique, for which a nanochannel drilled at the tip apex is used to deposit liquid from a reservoir defined on the top of the cantilever (for a review of these methods refer to chapter 12). Besides its applications for nanopatterning, the NADIS method is a unique method to study liquids at submicron scale and, more particularly, liquid meniscus with controlled dimensions. The capillary force curve experienced by the tip during the deposition and measured with AFM is a good way to assess calculation methods and finally to get more insight into the liquid transfer mechanism from the reservoir to the surface. ... [Pg.324]

The phenomenon of the loading and breakdown of the molecular strands has been studied by various methods. Optical and electron micrographs of crazes are shown in most of the cited references. Examples have been reproduced in Figures 9.8—9.10. Investigations of the craze shape by interference microscopy [15,155, 177] have also been discussed. At this point some results will be reported which have been obtained by thermal measurements [31, 50, 184—186], from analysis of the influence of molecular weight on crazing [11,15,65, 79, 146,178], through acoustic emission [174, 188], and by the ESR technique [189—190] respectively. [Pg.288]
