Representations associate

These states are catted t2g and eg, respectively, according to the nsnal notation based on the irredncible representations associated with these levels (see Chapter 7). [Pg.270]

Usually, an individual VB structure assembled from the localized bonding components does not share the point group symmetry of the molecule anymore. However, the overall VB wavefunction, PVB, should retain the same symmetry properties as the MO wavefunction (in the sense of full Cl, they are in fact identical). Therefore, TVs can be classified by an irreducible representation associated with a given point group. In order to sort vFra by symmetry, a project operator can be introduced as follows ... [Pg.174]

Chemoinformatics is characterized by the use of large amounts of information. Specific ways to represent the molecules, and to organize and analyze the data have been and continue to be developed. There are different ways to represent the molecules, and they can be classified according to the information that they encode. The most basic level corresponds to representations that depend on or are associated with one dimensional (ID) representation, such as molecular weight. The next level corresponds to the 2D representations associated with the connectivity of the molecules without the consideration of the stereochemistry. In 3D methods the incorporation of stereochemistry conveys not only the specification of the chirality of stereogenic centers but also the possible conformation or conformations. In this regard, the research fields dedicated to conformational analysis have an important impact in reactivity prediction, molecular design, and stability. Examples of ID, 2D, and... [Pg.36]

PH does not depend on Z just as the waveftmction V/ii does not. It will prove useful to consider also the time evolution of the density operator in the interaction representation associated with some suitable decomposition of H, H = Hq + V. This representation of p is defined by... [Pg.352]

A character table provides a complete list of the irreducible representations associated with a given point group, as well as other useful information. The appearance of these tables, which is identical for all point groups, is illustrated below for the C2V (e.g. H2O) and C3V (e.g. NH3) point groups. [Pg.217]

A more realistic and practical graphical representation associating fiber length with practical upper count limits (i.e., the upper linear density limit to which a fiber will spin commercially) must take account also, as has been said already, of the fiber fineness. See Table 2, which is based on a short staple ring spun system. [Pg.437]

The following situation proper for the temporal evolution compatible with the system equilibrium states, would be the group of the weak closure automorphisms, U)", of the space U in the cyclic representation associated to the state co. [Pg.372]

For example, a tetrahedron corresponding to harmonic representation associated to s and p orbital t5T)es, carrying the orbital quantum number taking the values /= 0,1, is a regular tetrahedron, describing four equivalent and equidistant states. In quantum theory, it is said that these 4 states, described by so- called hybridization spi, are forming an orthogonal basis. [Pg.371]

Is symbolically listed the molecular orbitals and is colhgated with the irreducible representations, associated to the decomposition of reducible representation of the primordial set of atomic orbitals, grouped (by one, by two etc.) according to the multiplicities with which the irreducible representations of symmetry group of the molecule appear in the decomposition of reducible representation of the atomic orbitals. [Pg.155]

The effect of white external noise in the master equation is then twofold First, a modification of the one-step transition probabilities (2.7), and second the introduction of new transition probabilities for n 1. In the thermodynamic limit, (2.6) becomes a partial differential equation for P(x,t) which involves derivatives of all orders with respect to x. It has the same form than (2.6) with the replacements Vo— - (r+(x)-r.(x)), r —. --D r+ Wx), —[4]. An expansion a-round this limit permits a systematic calculation of finite size effects. Alternative formulations of (2.5) and (2,6) can be given in terms of the generating function and Poisson representation associated with (2.1). [Pg.162]
