dear Giovanni,
I'm a bit confused...
due to Gauss theorem, doesn't all the [A] procedure boil down to be
the integral of the
ionic+electronic charge inside the vdW radius ...
I'm not sure I got what the RESP proceure does..

Dear Giovanni
Many thanks for your kind attention and very detailed answer. It has
raised up our knowledge around the topic.

As for point charges, here is a small recipe for isolated
molecules (see below) for the ESP/RESP procedure [A].
Reference is Bayly et al, J. Phys. Chem., 97, 10269 (1993).
Final point charges for organo-metallic molecules compare
fairly well with standard or published values.

Dear David,
the projwfc.x postprocessing code computes the so-called "Lowdin charges"
(at the end of the output), maybe that's something similar to what you want.

Dear All
I am trying to calculate the point charge and the point spin density on each
atom of a unit cell, certainly "WITHOUT" considering a 3D vector which is
necessary as described in INPUT_PP guide file. Calculating the point charges
and spins is customary in any quantum chemistry packages and
