Recently developed routine, PolaBer [1] allows to calculate atomic polarizabilities, and therefore group polarizabilities, based on the definition of atomic dipole moments given by Bader [2]. The routine uses the results of QTAIM partitioning of electron densities. According to QTAIM theory each atomic contribution can be expressed as a sum of
