    • 3h configurations using ATZfc, AQZfc, and A5Zfc. The resulting N-H bond lengths were 0.997 554, 0.996 018, and 0.995 577 Å respectively. They deviate from the directly optimized bond lengths in Table I by only +0.000 025, - 0.000 006, and -0.000 020 Å, respectively. This indicates the precision of the interpolation. The corresponding deviations in the total energies are +0.000 029, +0.000 028, and +0.000 047 a.u., respectively.

    • The bond length takes the following values: [0.60, 0.70, 0.80, 0.85, 0.90, 0.95, 0.97, 0.99, 1.01, 1.03, 1.05, 1.07, 1.09, 1.11, 1.15, 1.20, 1.25, 1.35, 1.45. 1.55, 1.65] A&ring. The angle takes the following values (the same as those in 1D-PES): [120, 119, 118, 116, 114, 112, 110, 109, 108, 107, 106, 105, 104, 103, 101, 99, 95, 90, 80, 70] deg.
