We report analyses and comparison of three high quality ab initio KRb a {sup 3}{sigma}{sup +} state potentials [Rousseau et al., J. Mol. Spectrosc. 203, 235 (2000); Park et al., Chem. Phys. 257, 135 (2000); Kotochigova et al., Phys. Rev. A 68, 011501 (2003)]. Eigenvalues for all vibrational levels and precision binding energies for high-lying levels (and corresponding triplet scattering lengths) are presented. By adjusting the inner wall of a potential, we show that we can reproduce measured scattering lengths of two isotopomers and predict scattering lengths of all isotopomers.
