So, do not worry.

The manual for Multiwfn suggests using atomic dipole moment corrected Hirshfeld charges for it. However I get strange results, on some atoms in which f+ is negative.

I'm using def2-TZVPD basis set, and I'm wondering if diffuse functions can make Hirshfeld charges meaningless as they do for Mulliken charges?

I'm sorry to cross post from another forum, but I highly hope that my question will be answered here.
