There is no doubt that this field, like few others, owes very much to its founder, Ronald Gurney, because of the fast start he gave it by applying quantum mechanics to interfacial electron transfers shortly after the publication of Schrodinger s wave equation (1926). The early seminal contributions (to which must be added that of J. A. V. Butler in the same period)22 founded quantum electrochemistry and led to its broader development by Gcrischer (1960), in particular the idea of the absolute scale of potentials and the equation...

The first objective of quantum theory is indeed aimed at the electron. The wave-mechanical version of quantum theory, which is the most amenable for chemical applications, starts with solution of Schrodinger s wave equation for an electron in orbit about a stationary proton. There is no rigorous derivation of Schrodinger s equation from first principles, but it can be obtained by combining the quantum conditions of Planck and de Broglie with the general equation6 for a plane wave, in one dimension ...

It can also be shown that Schrodinger s wave equation is none other than a form of the classical differential equation for a wave phenomenon in which the new feature is to be found in the application of it to electrons by means of the experimentally verified De Broglie relation which, in turn follows, as was seen, from a combination of the fundamental relations of Planck and Einstein in the form Av = me2 (p. 107). 

The solution of Schrodinger s wave equation for the hydrogen takes place in broad outline by the equation being separated into three equations, each of which depends on only one of the variables. The simplest one is that dependent on [Pg.118]

In place of the above intuitive solution the result can also be deduced from Schrodinger s wave equation. 

This equation is Schrodinger s wave equation, where h is Planck s constant and H is the Hamiltonian of the system to be investigated. The Schrodinger equation is a deterministic wave equation. This means that once ip t = 0) is given, ip t) can be calculated uniquely. Prom a conceptual point of view the situation is now completely analogous with classical mechanics, where chaos occurs in the deterministic equations of motion. If there is any deterministic quantum chaos, it must be found in the wave function ip. 

The next most familiar part of the picture is the upper right-hand corner. This i s the domain of classical applied mathematics and mathematical physics where the linear partial differential equations live. Here we find Maxwell s equations of electricity and magnetism, the heat equation, Schrodinger s wave equation in quantum mechanics, and so on. These partial differential equations involve an infinite continuum of variables because each point in space contributes additional degrees of freedom. Even though these systems are large, they are tractable, thanks to such linear techniques as Fourier analysis and transform methods. 

Solutions of Schrodinger s wave equation give the allowed energy levels and the corresponding wavefunctions. By analogy with the orbits of electrons in the classical planetary model (see Topic AT), wavefunctions for atoms are known as atomic orbitals. Exact solutions of Schrodinger s equation can be obtained only for one-electron atoms and ions, but the atomic orbitals that result from these solutions provide pictures of the behavior of electrons that can be extended to many-electron atoms and molecules (see Topics A3 and C4-C7). 

Th.e refinements of the theory, which have been worked out in particular by Houston, Bloch, Peierls, Nordheim, Fowler and Brillouin, have two main objects. In the first place, the picture of perfectly free electrons at a constant potential is certainly far too rough. There will be binding forces between the residual ions and the conduction electrons we must elaborate the theory sufficiently to make it possible to deduce the number of electrons taking part in the process of conduction, and the change in this number with temperature, from the properties of the atoms of the substance. In principle this involves a very complicated problem in quantum mechanics, since an electron is not in this case bound to a definite atom, but to the totality of the atomic residues, which form a regular crystal lattice. The potential of these residues is a space-periodic function (fig. 10), and the problem comes to this— to solve Schrodinger s wave equation for a periodic poten-tial field of this kind. That can be done by various approximate methods. One thing is clear if an electron... 

We have said that the fourth (spin) quantum number is not required by Schrodinger s wave equation. However, in 1928 Dirac derived a system of quantum mechanics, involving relativity, and he actually obtained terms which corresponded to this quantum number. His theory was also responsible for the prediction of the positron (a particle of equal mass to the electron but of positive charge). Unfortunately, his theory is so mathematically complex, that it has been of much less value than that of Schrodinger.

The confinement of a particle results in the quantization of its energy levels. Said otherwise, whenever a particle is attracted to or confined in space to a certain region, its energy levels are necessarily quantized. As discussed shortly, this follows directly from Schrodinger s wave equation.

In this chapter we shall consider atoms or ions which have a single electron. These include the hydrogen atom, He" and LP ". The solutions of Schrodinger s wave equation for such systems provide important information on the way in which an electron moves around the nucleus. The actual trajectory followed by an electron cannot be known in detail because of the operation of the uncertainty principle, but the wavefunctions obtained from the Schrodinger equation provide probability dis-...
