J. Korchowiec et al., RELAXED FUKUI FUNCTION INDEXES AND THEIR APPLICATION TO CHEMICAL-REACTIVITY PROBLEMS, Chemical physics letters, 222(1-2), 1994, pp. 58-64
The concept of the relaxed Fukui function indices at 'atoms in molecul
es' resolution is introduced for a general partition of a molecular sy
stem into closed subsystems and the corresponding combination formulae
are derived. It is shown that for such defined quantities the charge
transfer energy does not depend on the way the system reaches equilibr
ium. Finally, some illustrative examples comparing rigid and relaxed F
ukui function indices are presented.
