## Abstract Bond‐order potentials provide a powerful class of models for simulating chemically reactive systems with classical potentials. In these models, the covalent bonding interactions adapt to the environment, allowing bond strength to change in response to local chemical changes. However, th

✦ Synopsis
In the context of the multipoint Pad& theory, the vsn der \Vaals coefficients obtained from the semi-empirical method are seen to be lower bounds. with a s@htIy different constraint, the method also gives upper bounds.

On the basis of the adiabatic connection formula we propose several approximations for the total correlation energy functional, which, in the limit of two separated neutral subsystems, correctly reproduce the van der Waals R y6 behavior. We have calculated the corresponding van der Waals coefficient
