The potential of mean torque, parameterized by the local interaction tensors Xa and Xc (assume to be cylindrical) for the aromatic core and the C C segment, respectively, can be mapped out at each temperature by fitting the observed quadrupolar splittings in the mesophase. Furthermore, the order matrix of an average conformer of the molecule can also be calculated.17 Now pn is needed to describe the internal dynamics. 

Figure 3.10 — Flow manifolds for implementation of flow-through biosensors. (A) Flow injection merging-zones manifold for the bioluminescence detennination of ATP. ATP standards (30 fiL) and luciferin (30 fiL) are injected into the buffered carrier streams, each pumped at 0.7 mL/min and synchronously merged 12.5 cm downstream. Distance from merging point to immobilized enzyme coil, 2.2 cm. (Reproduced from [59] with permission of Elsevier Science Publishers).

The DSC thermogram of a representative star block showed two TgS corresponding to the PIB (at -67 °C) and PpClSt (at 127 C) segments. The star block showed high thermal stability. The 5% decomposition temperature, Tj, was... 

Exercise 12-23 A conformation of cyclooctane called boat-boat can be formed by having two gauche C—C—C—C segments, as shown in Figure 12-19. As drawn, this conformation has all hydrogens staggered and normal C-C-C bond angles. Explain why it is not a favorable conformation. Use of models will be very helpful. 

In both the heavy chain and X chain loci of mice and humans, there are a number of C as well as J gene segments. However, in the heavy chain loci, all the J s are clustered separate from the C s whereas in the X loci, each C segment is preceded by a J segment. In the case of heavy chains, any of the 7H can, at least in principle, be expressed in association with any of the CH, whereas in X chains, J -C pairing is fixed. 

Faces of double bonds are similarly homotopic when they can be interchanged by operation of a symmetry axis. (Since there are only two such faces, the pertinent axis must, of necessity, be of even multiplicity so as to contain C2.) Thus the two faces of acetone (Fig. 10) are interchanged by the operation of the C2 axis (the molecule is of symmetry C2v) the two faces of ethylene (Z)2h) are interchanged by operation of two of the three C2 axes (either the one containing the C = C segment or the axis at right angles to the first one and in the plane of the double bond). 

Class switching When the complete heavy chain gene shown in Fig. 4 is transcribed, it generates a heavy chain for an IgM antibody since it is always the first C segment after the recombined VDJ (in this case CJ that is transcribed. To switch to making a heavy chain for a different antibody class, say IgA, the lymphocyte DNA has to undergo yet another recombination event that moves Ca next to...
