McKean 182> considered the matrix shifts and lattice contributions from a classical electrostatic point of view, using a multipole expansion of the electrostatic energy to represent the vibrating molecule and applied this to the XY4 molecules trapped in noble-gas matrices. Mann and Horrocks 183) discussed the environmental effects on the IR frequencies of polyatomic molecules, using the Buckingham potential 184>, and applied it to HCN in various liquid solvents. Decius, 8S) analyzed the problem of dipolar vibrational coupling in crystals composed of molecules or molecular ions, and applied the derived theory to anisotropic Bravais lattices the case of calcite (which introduces extra complications) is treated separately. Freedman, Shalom and Kimel, 86) discussed the problem of the rotation-translation levels of a tetrahedral molecule in an octahedral cell. [Pg.72]

There are several important implications of this result the TD functional theory and the Baym functional theory are versions of the many-body theory in that they invoke different trial functionals in obtaining the stationary solution of the same variational functional, namely, the action functional. The two theories explore the optimization of the action functional in terms of different functional variables the TD functional employs density, current, ion-coordinates, etc. while the -derivable theory employs the two-point functions such as the Green functions associated with electrons, ions, etc. The above demonstration shows that different optimization strategies may be employed to explore the stationar-ity of the action functional. [Pg.207]

A potential advantage of the physical approach to boundary-layer theory is that it forces an emphasis on the underlying physical description of the flow. However, unlike the asymptotic approach presented here, the physically derived theory provides no obvious means to improve the solution beyond the first level of approximation. Provided that the physical picture underlying the analysis is properly emphasized, the asymptotic approach can incorporate the principal positive aspect of the earlier theories within a rational framework for systematic improvement of the approximation scheme. [Pg.698]

The approach toward the solution of biochemical problems in the past has been largely, and of necessity, deductive. However, model building and the application of material analogues are becoming increasingly important for the elucidation of fundamental problems of biochemical structure and reactivity. While models help us to derive theories supported by choice criteria which appeal to the models as empirical data (I), they also provide independent information which often leads to new areas of research and to significant discoveries outside the initially set research objective. [Pg.2]

An overview of the Polarizable Continuum Model (PCM) for the modelling of solvent effects on the state and the properties of quantum mechanical molecular systems is presented. The main theoretical and numerical aspects of this method are presented and discussed, together with its extension to the derivative theory. We present some selected applications concerning the evaluation of molecular response properties, and of the corresponding spectroscopic quantities, of different solvated systems. [Pg.1]

The GIAO method is used in conjunction with analytical derivative theory in this approach the magnetic field perturbation is treated in an analogous way to the perturbation produced by changes in the nuclear coordinates. In this framework, the components of the nuclear magnetic shielding tensor are obtained as ... [Pg.49]

One has to keep in mind that such a derivation always implies some assumptions concerning the stationarity of the analytical system and particularly the stationarity of the noise. In general, stationarity and the absence of a deterministic drifting baseline is assumed, although some derived expressions in the general form are valid for non-stationary noise. However, the derived theory can be used as a basis for the calculation of the remaining uncertainty in the case of a correction procedure for deterministic (for instance linear) baseline drift. [Pg.127]

In the previous chapter, the fundamentals of the Kohn-Sham method and its derivative theories have been explained without referring to the specific forms of exchange-correlation functionals used. The Kohn-Sham method is an established quantum theory based not only on electron density but also on a rigorous exchange-correlation functional. It is therefore difficult to assess the reliability of the Kohn-Sham method and its derivative theories without specifically considering the exchange-correlation functional used. In this chapter, let us examine the exchange-correlation functionals that have thus far been developed, with their features and problems. [Pg.101]
