As the number of basis functions increase, so does the computational cost. Table lists the relative CPU time for each CCSD(T) single-point energy calculation for three example molecules. C4H4 is one of the most expensive systems in the current study, whereas C6H12 and C6H12O6 are included as examples of larger, more challenging systems on which to perform a CCSD(T) calculation, and we note that C6H12O6 was too big for us to perform CCSD(T) calculations with jun/jul/aug-cc-pVQZ basis sets. For DZ, the jun calculations reduce the cost as compared to aug calculations by a factor of 3 to 5. The other comparisons show smaller but still significant ratios. To put things into perspective, it takes two and a half days for a CCSD(T)/jun-cc-pVQZ calculation on C6H12, and a CCSD(T)/aug-cc-pVQZ calculation would take well over 6 days for completion. A CCSD(T)/aug-cc-pVTZ on C6H12O6 takes almost 11 days of CPU time, as compared to less than five days for jun-cc-pVTZ. The new science that can be explored with this procedure includes any problem where such cost savings make the calculations more practical. calculations in Table . This is because TZ calculations, being more resource-intensive than DZ calculations, dominate the total computation time for both DZ and TZ calculations.
