[SIESTA-L] Grimme parameters

[Mohammad Khazaei]

Dear SIesta users,

Does anyone know what are the units of the parameters in the MM.Potentials 
block?
In the paper of Stefan Grimme (J. Comput. Chem. 27, 1787 (2006), 
the C6 parameters are given in J/mol nm^6  and the van der Waals radii of 
elements in Ang. 
In the Siesta manual the MM.UnitsDistance is Ang and MM.UnitsEnergy is eV.
Does it mean that in the MM. Potentials block, the C6 parameters should be 
given 
in eV Ang^6 and the van der Waals radii in Ang?

Thanks for your help.

Sincerely yours,
Mohammad
