In the literature, the van der Waals parameter for I is 1.892 Å [S. Grimme, J. Comp. Chem. 27, 1787 (2006)].
The Turbomole output, however, claims that the value used is 3.2503290 (1.720 Å) in the DFT+D.
Which one is correct,
the literature value (which seems to be the same as for element Te)
or the implemented value (which seems a bit small when compared to series F-Cl-Br: 1.287-1.639-1.749)?
