On the definition of bond orders at correlated level
Most often bond orders have heuristically been defined. In this work we follow a rigorous theoretical procedure looking for an appropriate definition of this concept. The study points out the exchange part of the pair density as a suitable starting point to set up a bond order definition, while the...

Most often bond orders have heuristically been defined. In this work we follow a rigorous theoretical procedure looking for an appropriate definition of this concept. The study points out the exchange part of the pair density as a suitable starting point to set up a bond order definition, while the definitions based on the fluctuation of electron populations should be restricted to noncorrelated state functions. Numerical calculations are reported to illustrate these conclusions. © 2003 Elsevier Science B.V. All rights reserved. |
