Coupled Cluster many Electron Theory and the Cohesive Energy of Large Systems Consisting of Weakly The first goal of this lecture in the summer school is to present the coupled cluster many electron theory formulated with the use of the Feynman-like diagrams. The second goal is to show that this theory is applicable to the calculation of ground state energy of large systems consisting of weakly interacting subsystems.

Electron States of Structurally-Disordered Chains,The great majority of calculations of the energy spectra of polymers have been performed on ideal chains. That is to say, they are the band structure calculations on extended periodic chains described by André and Delhalle in this volume.

LCAO Methods for Band Structure Calculations of Polymers, the point of view of structural materials; biopolymers play a fundamental role in life process and molecular crystals built up from polymers like (SN). or the TTF-TCNQ system exhibit special physical characteristics. It is now hoped that more emphasis will be given to the synthesis of those polymers which present specific features.

X-Ray Photoelectron Spectroscopy and its Application to Polymer Electronic Structure Studies,ure studies of molecules, solids and surfaces. Perhaps because of the length of its explicit name, X-ray photoelectron spectroscopy has become popular under the acronym E.S.C.A. (Electron Spectroscopy for Chemical Analysis).

Fourier Representation Methods in Electronic Structure Studies of Crystals and Polymers,eceive more attention is the effect of neighboring groups on the charge distribution in the vicinity of each atom of the system. The other feature, often not explicitly discussed, is the long-range effect of the inifite amount of charge (of both signs) of which the system is composed.
