This dictionary puts the pleasure back into word-seeking. Every time you look at a page you get a bonus - a panel telling you everything about a particular word or expression. It is, therefore, a dictionary to be read as well as used for its concise and up-to-date definitions. 

Eddy Currents ttike their name from the swirls (eddies) observed in turbulent water flow. The Greek mythology tells us about Charybdis. A monster eddy current between Italy and Sicily whose attractive field pulled unwary sailors to their destruction. Our kind of eddy currents are usually not so dangerous, they flow in electrical conductors and are a branch of Electromagnetics. Where does that spring from Could it make eddy currents the very oldest NDT technique ... 

La sensibilite aux defauts et autres parametres de controle peut etre amelioree par le choix optimal de la sonde. II apparait, apres etudes des differents types de sondes (ferritiques, acier doux, isolant) avec des geometries differentes (plate, conique,. ..), necessaires de souligner que le succes d une recherche de faisabilite depend en grande partie de la bonne definition des capteurs de mesure, de telle sorte que ceux-ci soient adaptes au probleme considere. 

There is little doubt that, at least with type II isotherms, we can tell the approximate point at which multilayer adsorption sets in. The concept of a two-dimensional phase seems relatively sterile as applied to multilayer adsorption, except insofar as such isotherm equations may be used as empirically convenient, since the thickness of the adsorbed film is not easily allowed to become variable. 

One feature of this inequality warrants special attention. In the previous paragraph it was shown that the precise measurement of A made possible when v is an eigenfiinction of A necessarily results in some uncertainty in a simultaneous measurement of B when the operators /land fido not conmuite. However, the mathematical statement of the uncertainty principle tells us that measurement of B is in fact completely uncertain one can say nothing at all about B apart from the fact that any and all values of B are equally probable A specific example is provided by associating A and B with the position and momentum of a particle moving along the v-axis. It is rather easy to demonstrate that [p, x]=- ih, so that If... 

Flowever, if only the Darling-Deimison conplmg is important for the conpled stretches, what is its importance telling ns about the internal molecnlar motion It turns out that the right kind of analysis of the spectroscopic fitting Flamiltonian reveals a vast amonnt about the dynamics of the molecnle it allows ns to decipher the story encoded in the spectrum of what the molecule is really doing in its internal motion. We will approach this spectral cryptology from two complementary directions ... 

One has seen that thennodynamie measurements ean yield infomiation about the ehange AS in an irreversible proeess (and thereby the ehanges in other state fiinetions as well).

Thus the average velocity decays exponentially to zero on a time scale detennined by the friction coefficient and the mass of the particle. This average behaviour is not very interesting, because it corresponds to tlie average of a quantity that may take values in all directions, due to the noise and friction, and so the decay of the average value tells us little about the details of the motion of the Brownian particle. A more interesting...

PES of neutral molecules to give positive ions is a much older field [ ]. The infomiation is valuable to chemists because it tells one about unoccupied orbitals m the neutral that may become occupied in chemical reactions. Since UV light is needed to ionize neutrals, UV lamps and syncln-otron radiation have been used as well as UV laser light. With suitable electron-energy resolution, vibrational states of the positive ions can be... 

Alternatively, in the gas phase one may be able to tell the direction of polarization in the molecular framework by looking at the intensity distribution among the rotational lines in a high-resolution spectrum. 

The synnnetry selection rules discussed above tell us whether a particular vibronic transition is allowed or forbidden, but they give no mfonnation about the intensity of allowed bands. That is detennined by equation (Bl.1.9) for absorption or (Bl.1.13) for emission. That usually means by the Franck-Condon principle if only the zero-order tenn in equation (B 1.1.7) is needed. So we take note of some general principles for Franck-Condon factors (FCFs). 

A kinked surface, like fee (10,8,7), can also be approximately expressed in this fomi the step plane (h k / ) is a stepped surface itself, and thus has higher Miller indices than tlie terrace plane. However, the step notation does not exactly tell us the relative location of adjacent steps, and it is not entirely clear how the terrace width M should be counted. A more complete microfacet notation is available to describe kinked surfaces generally [5]. 

Not only can electronic wavefiinctions tell us about the average values of all the physical properties for any particular state (i.e. above), but they also allow us to tell us how a specific perturbation (e.g. an electric field in the Stark effect, a magnetic field in the Zeeman effect and light s electromagnetic fields in spectroscopy) can alter the specific state of interest. For example, the perturbation arising from the electric field of a photon interacting with the electrons in a molecule is given within die so-called electric dipole approximation [12] by ... 

The main diffieulty with DFTs is that the Hohenberg-Kolm theorem shows that tire ground-state values of T, Fgg, V, ete are all unique fiinetionals of the ground-state p (i.e. that they ean, in prineiple, be detemiined onee p is given), but it does not tell us what these fimetioiial relations are.

An alternative approximation scheme, also proposed by Bom and Oppenheimer [5-7], employed the straightforward perturbation method. To tell the difference between these two different BO approximation, we call the latter the crude BOA (CBOA). A main purpose of this chapter is to study the original BO approximation, which is often referred to as the crude BO approximation and to develop this approximation into a practical method for computing potential energy suifaces of molecules. 

The next question is how to represent the reacting bonds of the reaction center. We wanted to develop a method for reaction classification that can be used for knowledge extraction from reaction databases for the prediction of the products of a reaction. Thus, we could only use physicochemical values of the reactants, because these should tell us what products we obtain. 

Trivial or trade namc.s can be stored and searched as character strings. Their use is the simplest and most intuitive way of storing chemical information. However, being not subject to strict rules, their formation does not reflect accurately the molecular composition. Hence, the structure of the searched compound cannot be derived from them. Thus, a name such as "Flexricin does not tell the user very much. Furthermore, many more than one trivial or trade name for a given compound usually exist. 

If the value of the asymptote is indeed found to be independent of x(0) and x(L), as equation (10.14) predicts, this tells us something about Che composition dependence of the matrix element in equation... 

Placing the 5-Iine control block above the geometry specification block of Exercise 5-4 gives the complete minimal input file for benzene, which we can call miubeuz.inniS (or anything else you like with the extension. mm3). Aside from the geometry block, there are two important differences between miubenz.mm3 and the file miuimal.mm3 for ethylene in File 4-la. One is the switch in column 61 of the first line, the other is the set of switches (hat constitutes the entire second line. The first switch tells the system... 

The first line gen (route section) tells the system that we want to define our own function. The lines 2, 3, and 4 are a blank line, program label (for human readers), and a blank line. The next line that is read by the system is 0 2, specifying that the ground state of H has a 0 charge and is a spin doublet (one unpaired election). The next line, h, specifies hydrogen, followed by a blank. 

The remainder of the input file gives the basis set. The line, 1 0, specifies the atom center 1 (the only atom in this case) and is terminated by 0. The next line contains a shell type, S for the Is orbital, tells the system that there is 1 primitive Gaussian, and gives the scale factor as 1.0 (unsealed). The next line gives Y = 0.282942 for the Gaussian function and a contiaction coefficient. This is the value of Y, the Gaussian exponential parameter that we found in Computer Project 6-1, Part B. [The precise value for y comes from the closed solution for this problem S/Oir (McWeeny, 1979).] There is only one function, so the contiaction coefficient is 1.0. The line of asterisks tells the system that the input is complete.
