Molecular orbital study on antiferromagnetic coupling mechanism in a silver （Ⅰ） complex

The mechanism of antiferromagnetic coupling in an Ag （Ⅰ） complex of nitronyl nitroxide is investigated by means of the broken-symmetry approach within the density functional method （DFT-BS）. The magneto-structural correlation and the single-occupied molecular orbital （SOMO） analysis reveal the existence of the antiferromagnetic coupling pathway along nitronyl nitroxide units via Ag （Ⅰ） ion, and that the Ag （Ⅰ） ion plays an important bridge role. The spin population analysis also shows the existence of spin delocalization along the ONCNO-Ag-ONCNO chain. It is found that the non-typical covalent bonds with major ionic character between Ag （Ⅰ） ions and oxygen atoms of nitronyl nitroxide units can be used to mediate the spin-spin interaction of nitronyl nitroxides.

Project Boundary Setting and Leakage Treatment in CDM Project

Project boundary setting and leakage treatment are two important issues to be considered when a clean development mechanism (CDM) project is being designed. There are still many uncertainties concerning these two issues. This paper reviews the concepts of project boundary setting and leakage in CDM projects, cites the types and sources of leakage, discusses the principles for determining leakage, and gives some proposed methods for dealing with leakage. A case study, using several steps to solve the boundary and leakage problems, shows how the analyzed principles and treatments can be implemented in a real project. Based on the result of the case study, the methods discussed are shown to be appropriate for settling leakage issues.
