It has been found that the Li quadrupole parameters x( Li) and /]( Li) are sensitive probes of solid state structures of organolithium compounds, for example with respect to aggregate size, solvation, ion pair structure and the X-Li-X structural angle. These results will be discussed in the following sections.

Analogously, in bis-histidine ferriheme proteins, cytochromes b (see Fig. 5.20B) [50,51], cytochromes C3 [52] and cytochromes C7 [53], the chemical shifts for each methyl proton at 298 K appear to be dependent on the

In the analysis of the topology of such nets we can look for a classification scheme that will allow one to uniquely assign equal nets (up to isomorphism) derived from totally different crystal structures. Remember that the topology is not influenced by the metrical properties of the structure (angles, distances), so that a 4-connected diamondoid net is such, even if highly distorted (the geometry around the nodes could be far from tetrahedral), and also, obviously, is not dependent on the chemical nature of each node/vertex.

Upper Structure and Seal The upper structure consists of vertical carbon steel structural angles welded to a top lifting ring and a lower horizontal plate. The upper structure provides support for the mechanisms in the upper part of the refueling penetration where the environment is relatively mild, i.e., low radiation and moderate temperature.
