Some minor additional coding is needed for SIESTA, I did it and can 
share.
Though, it's very rough, since I discontinued to work with it since 
Bader analysis gave me very similar results to Mulliken and Andrei's 
tool.


I cannot agree that observing the relative change in Mulliken charges 
instead of absolute values would be correct. I had experience that DZP 
showed transfer of charge from surface to molecule, while TZP showed 
the opposite (though the charge transfer itself was very smal - about 
0.1e)


Was this an effect only in the Mulliken populations, or was it something 
from the calculation?  Did you checked was was really happening with the 
charge transfer?

Dear Chaohao,

Perhaps you can find the message what you want from the following
two papers:
J. Mol. Struct. 742, 147 (2005).
Surf. Sci. 482, 625 (2001).

Wish you luck!

Best Regards, Huang Renzhong

Dear Siesta users,



Who can provide me the pseudopotential and basis set of Chlorine (Cl),
because I need it in my following first principles molecular dynamics
calculation?

Any hints on constructing them is also welcome!



Thanks in advances!



Best regards
