which consequently describes the asymptotic limit of the energy for consecutive enlargements of the basis set. This stands under the assumption that each increment of the basis set contains all functions covering the atomic angular momentum up to L. However, choosing the atomic angular momentum as the parameter for assessing energy convergence is questionable when generalizing to molecules. Moreover, this quantum number is not consistent with the construction of the (aug-)cc-pVXZ bases that rather involves successive increments of functions with different angular momenta (Section II C).
