Figure 2.7, for example, shows how a 2" -order radius r = 1 rule 4> may be converted into a F -order radius r = 2 rule Effective values d 0,1,..., define the states of the single remaining cell of a two-state collapse in time, and extra sites are added on to either side of the original neighborhood. [Pg.43]

Although the (111) face of fee metals is of the lowest surface free energy — a fact which may explain the reconstructions of the (100) and (110) faces —, the (111) face itself may also reconstruct Au(l 11) is normally reconstructed with a structure that may nevertheless still involve the hexagonally close-packed layer geometry (since extra sites of hexagonally arranged spots appear in LEED), but with a lattice constant different from that of the bulk . ... [Pg.120]

A general account of prototropic tautomerism has been given in Chapter 2.01. The situation in the non-aromatic polyheteroatom systems is generally quite complicated particularly if the system has more than one nitrogen atom to provide extra sites for the tautomeric proton. Only the important diuretic benzothiadiazine dioxides (46) (47) have... [Pg.1055]

Resin-bound nitroalkenes were synthesized via a Knoevenagel condensation of resin-bound nitro acetic acid with aryl and alkyl substituted aldehyde (Scheme 9.29). In this way an extra site of diversity can be introduced into the cycloaddition products of these nitroalkenes. Furthermore, the resin-bound nitroalkenes can serve as activated alkenes in other cycloaddition reactions (Diels-Alder, 1,3-dipolar cycloaddition, [2 + 2] cycloaddition) and therefore lead to the solid phase synthesis of other interesting compoimd classes (see also Scheme 9.3, Sect. 9.2). Formation of the resin-bound nitroalkenes 73a-e was realized in one step via a microwave-assisted condensation of aldehyde 72a-e (10 equiv.) with the resin-bound nitro acetic acid 71, followed by dehydration of the intermediate y -nitroalcohol [6] (Scheme 9.29). THF was used as the solvent in order to obtain optimal diffusion of the aldehyde in the polystyrene resin. [Pg.301]

In a variant of this model wc have reduced the size of the core, added an extra site to each chain to model the Si(Me)2-0-Si(Me)2 groups and extended the length of the spherocylinders used to giw an aspect ratio... [Pg.76]

Let us now consider radicals obtained by adding an extra site on a polyacene or fused polycyclic hydrocarbons. [Pg.368]

Independent of the mode of activation (membrane bound CF1 by energization of the membrane, isolated enzyme by DTT at 63° or by DTT at 25°) an extra capacitiy for eosin binding was induced. The inding of eosin-SCN to extra sites in the beta-subunit inhibited only the Ca -ATPase activity but not the synthase ac vity. If eosin-SCN was additionally bound to the gamma-subunit, both the Ca -ATPase as well as the synthase activity were inhibited. It is worthwhile to note, that extra binding of CF1 was prevented by high concentrations of ATP (5-10 uM) but not by ADP or P.. The binding of eosin-SCN to nonactivated CF1 was not inhibitory for eac of its activities up to a ratio of 7 moles of eosin-SCN/mol CF1 (7,8). [Pg.580]

Here f represents extra sites, which might be required for the substrate-modifier complex to be formed compared to the site requirement for them separately. [Pg.99]
