fukui functions revisited
Dear CCLers,
Following the Fukui function discussion initiated by H. K. Yeoh, it
may be
useful to recall the work of Robert Parr, defining the Fukui function
as the
second cross derivative of energy with respect to the number of
electrons
and the external potential. Defined this way, the Fukui function is a
local
response function and it may be computed in different ways, as shown by
the
recent works of :
Ayers and Parr, J. Am. Chem. Soc., 2000, 122, 2010
Michalak et al., J. Phys. Chem. A., 1999, 103, 762
Korchowied and Uchimaru, J. Phys. Chem. A., 1998, 102, 10167
If "the frontier orbital concept was criticised on not having
a real theoretical basis", it must be pointed out that this
definition of a
fukui fiunction goes "beyond" the frontier orbital
approximation. Does the
Fukui function really deserve a criticism adressed to frontier orbital
?
