Relaxed Fragment Transformation of Reactant Hardness Matrix

3 Relaxed Fragment Transformation of Reactant Hardness Matrix 

As we have already remarked in the preceding section, the relaxed hardness matrix of M = (A B) (Eq. (la)), 

by transforming the AIM-electronegativity equalization equations, dfi = d Nif = — 5Ntj, one obtains their REM representation  

We would like to emphasize that the REM basis vectors, = (dkel = tk, are not orthonormal, since their metric
