The linear-algebraic/optical-potential method is applied to low-energy 2Sigma g + and 2Pi g e + N2 scattering in order to understand the nature of the correlation effects in these two symmetries. The calculations clearly show that the two symmetries are dominated by quite different physical effects. The 2Sigma g + scattering is sensitive to long-range dipole distortions of the N2 core, while 2Pi g symmetry is critically dependent on short-range correlations which conserve the Sigma g + symmetry of the N2 core electrons. Quantitative results which support these conclusions are presented, and implications of the calculations on the construction and use of model potentials and polarized orbitals are briefly discussed.
