Remember from basic quantum mechanics that to completely describe an electron its spin needs to be specified in addition to the spatial coordinates. The spin coordinates can only assume the values Vr, the possible values of the spin functions a(s) and fits) are raO/i) = (K- /i) = 1 and a(-V4) = (K /i) = 0.

The basic quantum-mechanical problem is to formulate the wave-like description of an electron moving in the electrostatic field of the nuclei and other electrons. If the potential energy of an electron at a point x, y, z) is V %, y, z), this is accomplished by solving the well-known Schrodinger equation for a wave function w(%, y. z)... 

The calculation of the PE surface is basically quantum mechanical. Accurate surfaces are used to show how the topography of the surface affects the reaction unit as it changes configuration across the surface. Predictions can be made, and these can be tested by molecular beams, spectroscopic techniques and chemiluminescence. 

Arriving subsequently at rigorous quantum mechanical descriptions, we have assumed that the reader has some preliminary knowledge of basic quantum mechanical formalism. We consider it methodologically important to illustrate the correspondence principle between quantum and classical concepts, in particular between the concept of coherence of the wave functions of magnetic sublevels, and the symmetry properties of spatial angular momenta distribution.

Gamow waves, even though standard quantum mechanical states remain embedded [6]. Although general Hamiltonians may not subscribe to dilatation analyticity, complex symmetric perturbations, as the specific situation dictates, have an additional appeal. In the forthcoming description, basic quantum mechanical physical law will rule at the same time classical mechanics takes over where and when appropriate. 

Obviously there are two approaches One from basic quantum-mechanical theory of the chemical species at hand, and the other from EPR experimental data The choice of matrices g that yield a given G is far from unique.d Note also that matrix g is not necessarily real or symmetric. 

We know from basic quantum mechanics that angular momentum is always quantized in half-integral or integral multiples of h, where h is Planck s constant divided by 2tt. For the electron spin, the multiple (or spin quantum number) is Y2, but the value for nuclear spin differs from one nuclide to another as a result of interactions among the protons and neutrons in the nucleus. If we use the symbol I to denote this nuclear spin quantum number (or, more commonly, just nuclear spin), we can write for the maximum observable component of angular momentum... 

In addition, basic quantum mechanical calculations have shown that the change in isotropic H chemical shift (SH) due to hydrogen bond formation can be attributed primarily to O-H bond polarisation [80]. Similarly, the change in 2H quadrupole coupling constant is also expected to be caused by O-H bond polarisation. It would therefore be interesting to explore correlations between SH and the O-H bond length (r0 H) and correlations between e2qQlhand r0 H> as r0. H... 

Basic quantum mechanical calculations (i.e., the Bloch equations) show that the general EPR resonance absorption (T) will have a Eorentzian line shape...
