Endoscopic Sleeve Gastroplasty, chemistry was mainly concerned with the study and understanding of its own chemical synthesis and mechanical properties. Besides their important role as plastics and in biological processes, polymers now appear to be more and more interesting from an electronic and magnetic point of view. They will

The corresponding expressions are given for both cases when either a closed-shell molecule, or an open-shell system forms the unit cell and the CO method is formulated als

There are, of course, many types of optical measurements: one and two photon absorption,. reflection, and Raman scattering, to just name some common methods. All of these

However, if one examines no more than the literature on polyethylene band structures, one finds papers by Imamura., Morokuma. and Clementi. in which some fundamental consequences of the molecular symmetry were not appreciated. It is therefore quite appropriate that we use the regul

Firstly, to introduce to a heterogeneous group of experimentalists and theoreticians the powerful experimental technique of ESCA for studies of structure and bonding in general. After reviewi
