This oscillatory behavior has a dramatic and detrimental effect on extrapolation to the canonical limit, as shown for L7 + bbr in Fig. . There, we compare the extrapolated DLPNO errors based on either def2-SVP or def2-SVPD data. (For the corresponding percentage errors, see Fig. .) The extrapolations based on def2-SVPD calculations are clearly unreliable and afford much larger errors than the input data, for every single complex in the data set. This is not observed for def2-SVP, where the (L/N) MP2 and (N/T) MP2 extrapolations are typically (though not always) more accurate than the input data.
