12. 6 = 34.6 a.u.
13. 6, and these are used for r > 13 a.u. This introduces a small inconsistency with the FCI/pVTZ fits of Ref. 6, where the corresponding coefficients were fitting parameters based on the r-range 3-13 a.u.
14. -3. Thus the hyperpolarizability term Δγ̄ is a negligible contribution to the results of Sec. II and it is neglected for the remainder of this paper.
15. 0 calculated from their data is almost twice that in Ref. 12, showing the delicate near-cancellation of overlap and dispersion contributions to this average.
16. 0 calculated with their model differs by less than 1% from the value given in Ref. 12.
