Of course, the papers chosen are personal choices and the volume makes no claim to being fully comprehensive. No doubt 23 different individuals would have selected 23 different papers, nor, by any means, are the selected papers the only ones published in Faraday journals that have had a lasting impact on physical chemistry. Nevertheless, we hope that they do leave an impression of how important these journals have been in the development of the scientific fields central to the interests of the Faraday Society and its successor. 

The butadiene bridge of octavalene (59) widens the angle at the central carbon the rather high field central carbon shows Jc(1)h == 207 Hz and the much lower field allylic carbon C(2) has a normal value Jq2)h = 1 2 Hz. From a comparison of the values of Jqh octavalene and 96 it appears that any correlation between the magnitude of Jqh and the probable angle between the three-membered rings is not securely established. 

Histology The parenchyma is formed from pluricellular trabeculae and two (or three) layers of hepatocytes, the width of which varies from location to location. The hepatocytes are rich in glycogen, often pleomorphic and enlarged, and usually show fine-drop)-let fatty deposits. No evidence of acinar architecture or Kupffer cells is found only very few preexisting and incorporated portal fields, central veins or bile ducts are detectable. There are numerous arteries and ectatic sinusoids the latter contain no Kupffer...

Scharifker [33] considered that two processes interact in the film formation kinetics the activation and the deactivation of sites on the substrate. Thus, the deactivation, caused by the development of a hemispherical diffusion field centralized at each nucleus, inhibits film growth in the neighborhood of the diffusion centers.

Fig. 20. Direct comparison of the output obtained from a thermocouple probe coated in silicon rubber against that obtained with the aluminium foil method in the same sound field (central axis of a Laborette 17 cleaner, water level 50 mm). The aluminium foil was sonicated for 30 s...

Figure 7-12. Age related deterioration (a) in static acuity under optimal (photopic), low illumination (Mesopic), and glare conditions, and (b) in dynamic visual acuity, ability to detect motion across the visual field (Central Angular Motion - CAM), and forward motion (Central Movement in Depth - CMD) (from Shinar and Schieber, 1991, data from Shinar, 1977).

To operate the MPI or LPI equipment at stable and reprodncable inspection conditions modern units are equipped with a monitoring and control system called "Quality Assurance Package" (termed QAP). The QAP System is ba.sed on an industrial PC with a bus system and field sensors. It ensures that process parameters important for the reproducability of the MPI or LPI are controlled an held between defined limits by a central computer system. It can be adapted to any old system, as well as integrated into new systems. 

The central equations of electromagnetic theory are elegantly written in the fonn of four coupled equations for the electric and magnetic fields. These are known as Maxwell s equations. In free space, these equations take the fonn ... 

The solute-solvent interaction in equation A2.4.19 is a measure of the solvation energy of the solute species at infinite dilution. The basic model for ionic hydration is shown in figure A2.4.3 [5] there is an iimer hydration sheath of water molecules whose orientation is essentially detemiined entirely by the field due to the central ion. The number of water molecules in this iimer sheath depends on the size and chemistry of the central ion ... 

The central quantity of interest in homogeneous nucleation is the nucleation rate J, which gives the number of droplets nucleated per unit volume per unit time for a given supersaturation. The free energy barrier is the dommant factor in detenuining J J depends on it exponentially. Thus, a small difference in the different model predictions for the barrier can lead to orders of magnitude differences in J. Similarly, experimental measurements of J are sensitive to the purity of the sample and to experimental conditions such as temperature. In modem field theories, J has a general fonu... 

Advantages. The experiment can be carried out with a conventional fast-spuming MAS probe so that it is straightforward to implement. For recording the satellite transition lineshapes it offers better signal-to-noise and is less susceptible to deadtime effects than static measurements. As the effects differ for each value, a single satellite transition experiment is effectively the same as carrying out multiple field experiments on the central transition. 

The measurement of surface forces out-of-plane (nonual to the surfaces) represents a central field of use of the SFA teclmique. Besides the ubiquitous van der Waals dispersion interaction between two (mica) surfaces... 

In the most connnonly employed mean-field models [25] of electronic structure theory, the configuration specified for study plays a central role in defining the mean-field potential. For example, the mean-field...
