The q-vSZP basis set, as described in Ref. 13, operates on the simple principle that the contraction coefficients of the primitive Gaussian functions depend on the chemical environment of each atom. Thus, every symmetry-unique atom in a molecule obtains an individual basis, enabling the AOs to "breathe". Since this fundamental concept remains unchanged in the revised version presented here, only a brief overview of the theory will be provided (for a comprehensive overview, refer to Ref. 13).
