The new aug-cc-pVnZ-PP-F12 (n = D, T, Q) orbital basis sets have been produced by augmenting the existing cc-pVnZ-PP-F12 sets with additional diffuse functions, keeping all other exponents in the basis fixed. As the parent cc-pVnZ-PP-F12 sets already contain diffuse s-and p-type functions from the aug-cc-pV(n+1)Z-PP sets, augmenting functions were only added for higher angular momentum shells already occupied in the cc-pVnZ-PP-F12 parent. It should be noted that the cc-pVDZ-PP-F12 basis contains f-type functions, but the purpose of these functions is for (optional) correlation of the outer-core d electrons, hence the decision was taken to only add diffuse d functions in the DZ case. As a single additional exponent is added for each angular momentum symmetry concerned, at the DZ level the parent basis is augmented by 1d exponent, 1d1f at the TZ level, and 1d1f1g at the QZ level. This process is analogous to the diffuse augmentation of the cc-pVnZ-F12 sets undertaken by Sylvertsky et al. The basis set composition for the new aug-cc-pVnZ-PP-F12 sets are summarized in Table , where they are also compared to the respective cc-pVnZ-PP-F12 composition.
