    • Chemical bonds between a pair of atoms can be identified by (3,-1) critical points (the so-called bond critical points, bcp) of the charge density. At such bcp's the gradient vector of p(r) vanishes and the Hessian matrix of ρ(r) at bcp has three nonvanishing eigenvalues, two of which are negative. The positive eigenvalue is associated with the bond path itself along which the charge density ρ(r) reaches a minimum at the bcp.
