K 2, definition

Now (L (Pg)) is not 2-definite (or even k-definite for any k ) and so P3 cannot be translated into any strongly equivalent monadic recursion scheme. [Pg.315]

On the basis of this general scattering behavior Kratky and Porod [ 1 ] predicted long ago that a plot of k P k) against k should exhibit a "transition from the asymptotic plateau for a Gaussian coil to the asymptote for a rod. The transition point may be defined as the point of intersection of the two asymptotes. Then, k, the value of k at this point, is equal to G/irq. Thus, q can be estimated if the two asymptotes are experimentally observable so as to be able to determine k definitely. This method has been applied to several flexible polymers. However, actual scattering curves do not always exhibit a distinct plateau region. [Pg.145]

For the network of stoichiometry [Mn Fe (ox)3], one encounters the rare situation of a bimetallic lattice in which both metal ions have the same electronic ground state, namely 3i/ , S = 5/2, T i. In this case, the compound has been found to mimic antiferromagnetic behavior. Thus the temperature dependence of the magnetic susceptibility is that of a classic two-dimensional antiferro-magnet, reaching a broad maximum at 55 K. Definitive evidence for this behavior comes from a neutron powder diffraction study, which revealed a simple collinear antiferromagnetic alignment of Mn and Fe moments parallel to the c-axis, or in other words perpendicular to the layers. [Pg.219]

In this case, the level of theory is almost irrelevant for evaluating the relative stability of the different sites (Table 13). The proton is preferably predicted at the Sin site. Li and Na cations are more stable when coordinated on the hexagonal prism (SII), whereas K definitely prefers the eight-member ring site (SnP) for steric reasons. [Pg.57]
