In this chapter, we shall explore the ghostly secondary images of the landscape, where the changes in various properties are depicted as changes in altitude. As this is in any case an imaginary kingdom, a land of chemists dreams, there need be no constraint on its portrayal except truth, and to the mind s eye the terrain may rise and fall according to the features we seek to portray. We have... 

The molecular structure of 9 at room temperature is similar to that at 173 K, but there is considerable metal atom disorder, which is shown in Fig. 9. The FeRu2 triangle resides on a site of 2/m crystallographic symmetry, so the disorder is more complex than in the previously discussed systems. There are two major Star of David components at 82% populations, and a second set of four positions containing the remaining metal atom density. The two Ru atoms in these secondary images lie considerably out of the plane of the main Star of David component, although the Fe atoms are coincident with the sites labelled Rul. It is proposed that... 

On the other hand, thinner slices can be used. This has the advantage of reducing partial volume effects and, if a very small slice thickness, e.g. 1 mm, is used, offers the option of performing secondary image reconstruction that is comparable to the axial source images in terms of spatial resolution.

Photography. Silver is of the utmost importance in photography, about 30% of the industrial consumption going into this application. Actually, the use of silver in photography is due to the ability of silver-halide crystals (i.e., especially silver bromide) to be photosensitive and undergo a secondary image amplification called development.
