As the cc-pV(n+d)Z orbital basis sets are obtained from cc-pVnZ with an additional d-function and a re-optimization of the existing d-function exponents, we approach the development of the cc-pV(n+d)Z/JKFit auxiliary sets by modifying the cc-pVnZ/JKFit sets. This was also motivated by the promising results of Ma et al. for sulfur. Initial testing revealed that the addition of s-, p-or d-type auxiliary functions to cc-pVnZ/JKFit had effectively zero effect on both δ EX and the total DF-HF energy.
