Numerical values of ∆r, ∆σ and Γ are listed in Table , up to n = 9 sets of diffuse functions, in both the CMO and the Boys-localized representations. (See Table for the Λ metric.) In the CMO representation, the value of Γ continues to grow as additional diffuse shells are added, driven mostly by grown in the value of ∆σ and reaching Γ CMO = 13.5 Å for the S 1 state and Γ CMO = 24.9 Å for S 3 , for n = 9 sets of diffuse functions.
