Figure 9.16 Symmetry relation between p orbital on N and d orbitals on the 3 Si atoms in planar (NSi3 compounds such as N(SiHj)3. |

The rate of formation of the degraded fragments, with the symmetry relation (82), is given by [Pg.142]

From the last expression the following symmetry relations can be deduced [Pg.408]

In considering whether a molecule is superimposable on its mirror image you may sense that the symmetry properties of the molecule should be able to give this information. This is, in fact, the case, and the symmetry-related mle for chirality is a very simple one [Pg.79]

Any symmetric object is built up from smaller pieces that are identical and that are related to each other by symmetry. An icosahedron can therefore be divided into a number of smaller identical pieces called symmetry-related units. Protein subunits are asymmetric objects hence, a symmetry axis cannot pass through them. The minimum number of protein subunits that can form a virus shell with icosahedral symmetry is therefore equal to [Pg.327]

The polarization state p = 1 is necessary but not, however, a sufficient condition for a nonzero P coefficient in the angular distribution. Recalling the general CGC symmetry relation [Pg.277]

It has been shown [48] that the related off-diagonal elements Mujjji and Mjji uj obey definite symmetry relations which must be maintained after the corrections indicated above have been applied. [Pg.72]

Other coefficients, which differ only in sign from the (7, have been introduced for tie purpose of simplifying the symmetry relations. For these we refer the reader to Bose s monograph, cited above. Numerical tabulations of (7-coefficients are now abundant.11 [Pg.408]

PbTX-1 also cx)ntains the intermolecular hydrogen bond between hydroxyl 013 and carbonyl 01 already discussed. Only for dihydro PbTX-1 was it possible to locate an 012 hydroxyl hydrogen atom position from difference electron density maps. In that structure a peak appeared at 1.1 A from 012 and 2.1 A from symmetry related 05. [Pg.162]

Note that II(p2) approaches a constant asp2 —> oo so that if we wish to calculate Kip) from Im Kip) we must use the once subtracted dispersion relations (10-72). We, furthermore, note that due to the symmetry relation (10-86), and (10-87) we can write the unsubtracted dispersion relation as follows [Pg.595]
