Physical magnitudes characterizing the electronic charge transfer are analytically the transmission coefficient and the localization length. It is shown that a set of delocalized states occurs at particular well-defined energies. The divergence of the localization length is investigated and a critical exponent 1 is found for the barrier case which differs with the results of literature. These results support the idea that the nature of the extended states depend on the typical nature of the correlation in disorder. On this basis, the conductance of disordered superlattices is investigated as well as the relative fluctuations of the transmission coefficient.

XRD diffraction patterns show that all samples have a pure single-phase cubic spinel structure over the whole composition range. From these patterns, the lattice parameters, crystallite size and porosity of these samples have been calculated and compared with those predicted theoretically. Most of the values were found to increase with increasing Cu content. Far infrared absorption spectra show high and low absorption bands corresponding to tetrahedral and octahedral sites confirming the single phase spinnel structure. The calculated force constants, K-t, and K-o for the two sites are found to increase with increasing Cu content and their relative values are consistent with bond length magnitudes at tetrahedral and octahedral sites.

Molecular structures, conformational energies, moments of inertia, dipole moments and vibrational wavenumbers have all been examined. The tested molecules are ethandial (glyoxal), propenal (acrolein), 2-methylpropenal (methacrolein) and some of their deuterated analogs. The parameters of the force field were developed in order to reproduce experimental values: structures, conformational energies
