Symmetric properties

After some transformations using the symmetrical properties of the potential profile, one finds... [Pg.410]

It is therefore possible to classify the various molecular orbitals according to their two independent symmetric properties which are as follows ... [Pg.26]

From the above expressions presented in this section, we can already conclude several interesting properties of the transformation A. First, Eqs. (27) and (28) show that it is nonunitary transformation, A A . Acmally, one can show that this transformation satisfies a more general symmetric property called star unitarity (see Refs. 5, 10, 13, and 14) ... [Pg.142]

If 0 0 and A 0, the excess functions do not exhibit symmetrical properties over the compositional field. In this case, the mixture is defined... [Pg.169]

Because the simple mixture has symmetric properties, the system defined by equations 3.205 and 3.206 can be easily solved. Setting X = 0.5, we have... [Pg.176]

Moreover, from the first-law (Maxwell-type exactness) relationship between mixed partial derivatives, as expressed by (8.80), we see that the (R R/) values also satisfy the symmetric property (9.27b) ... [Pg.334]

For multichannel scattering where there are two or more open channels, the S matrix is a true matrix with elements Sy and the cross section for the transition from channel i to channel j is proportional to 5y - Sy 2. The symmetry of collision processes with respect to the time reversal leads to the symmetric property of the S matrix, ST = S, which, in turn, leads to the principle of detailed balance between mutually reverse processes. The conservation of the flux of probability density for a real potential and a real energy requires that SSf = SfS = I, i.e., S is unitary. For a complex energy or for a complex potential, in general, the flux is not conserved and S is non-unitary. [Pg.182]

HLADH converts a wide range of substrates. For the predicition of the stereoselectivity of reduction reactions, originally Prelog s diamond lattice model was applied, which is based upon the characteristic properties of the ADH of Curvularia falcata [37]. This model describes the stereospecificity of HLADH catalyzed reductions of simple acyclic substrates such as aldehydes. Later on, for more complex acyclic and cyclic substrates, a cubic-space model of the active site was developed [38,121]. Other models are based upon symmetric properties [122-125] or upon a refined diamond lattice model [126-129]. [Pg.159]

Let us consider a shallow fluidized bed combustor with multiple coal feeders which are used to reduce the lateral concentration gradient of coal (11). For simplicity, let us assume that the bed can be divided into N similar cylinders of radius R, each with a single feed point in the center. The assumption allows us to use the symmetrical properties of a cylindrical coordinate system and thus greatly reduce the difficulty of computation. The model proposed is based on the two phase theory of fluidization. Both diffusion and reaction resistances in combustion are considered, and the particle size distribution of coal is taken into account also. The assumptions of the model are (a) The bed consists of two phases, namely, the bubble and emulsion phases. The voidage of emulsion phase remains constant and is equal to that at incipient fluidization, and the flow of gas through the bed in excess of minimum fluidization passes through the bed in the form of bubbles (12). (b) The emulsion phase is well mixed in the axial... [Pg.96]

In general for a /-component fluid mixture one has a (z/ + 3 l 1)-component set p yd of dynamic variables, containing //-component of the number densities / k,a, the three components of the total current density Jk, and the total energy density E. However, as follows from the symmetric properties, the number ttk.a and energy densities are coupled only with the longitudinal component of Jk, directed along k. This is due to the space isotropy of the system. As a result, one may split the set of the hydrodynamic variables into two separate subsets ... [Pg.112]

The field of the Og cube results in the splitting of the 5d components into eg and t2g in the O/j symmetry. However, the area ratio between these peaks is far from 2 3 due to their multiplicities because the cross sections for the X-ray absorption are determined by the strength of the confinement of the quasi-bound states. This splitting of the B and C peaks arises from the different scatterings by the oxygen cube, though only the symmetric properties are the same as those in the crystal field. [Pg.119]

Briefly, when using orthogonal compactly supported wavelets it is not straightforward to obtain a wavelet which has symmetrical properties [7,12] and allows for an exact reconstruction. That is of course with the exception of the trivial Haar wavelet. Biorthogonal wavelets relax the assumptions of orthogonality, and allow for a perfect reconstruction with symmetrical wavelets. [Pg.79]

In weak interactions, where neutrinos are involved, the symmetric property (i.e. the parity) is not conserved. This is related to the fact that the neutrino spin is 100% polarized anti-parallel to its momentum (helidty = — 1) since the neutrino mass fe nearly zero. (Helidty of the anti-neutrino is -fl however, i.e. its spin is... [Pg.95]

The formation of crystal clusters, aggregates or conglomerates which possess no symmetrical properties is probably more frequently encountered in large-scale crystallization than the formation of twins. Relatively little is still known... [Pg.26]

The situation is different when coupling two equivalent electrons these are electrons that belong to the same shell. In this case, the coupled states are already eigenfunctions of the exchange operator as a result of the special symmetrization properties of the coupling coefficients for direct squares. Equation (6.10) will take the following form ... [Pg.124]

The formation of banded textures in thin-film samples of solutions of hquid crystalline polymers (LCPs), subjected to shear, has been reported in the literature since 1979 [15]. Because of the symmetrical properties of the liquid crystal solutions, large domains of weU-oriented polymer chains are formed during shear flow, while defects are squeezed into small regions. The shear accounts for an additional energy stored in the solution. When the shear is stopped, the system will first relax with a characteristic time fb to a transient state. In this state the distortion energy is minimized, and the orientational order is kept, resulting in a banded stmcture. This behavior is observed only if two conditions are fulfilled [16] ... [Pg.403]

The spin quantum number was introduced, leading to a discussion of the Pauli exclusion principle and the anti-symmetric properties of real wave functions. [Pg.58]

Figure 4.7.4(b) shows an example of the viewing angle dependency of the transmittance for typical TN-LCDs. In part (a), the strong viewing angle dependency in part (b) is not observed. Moreover, each curve shows symmetrical properties. [Pg.124]

In order to model transport in the membrane, we need the fluxes of each species in terms of the driving forces. At this point, equation (8.67) gives us the driving forces (i.e., gradients in concentration, activity, potential, pressure, etc.) in terms of the fluxes. We need the inverse equations. We defined the friction coefficients in equation (8.67) to use their symmetric property... [Pg.333]
