Abstract

We present a pseudospectral formulation of the single reference, closed shell double excitation configuration interaction method using a generator state self-consistent electron pair approach. The method scales as O(n ²N³), compared to the conventional scaling of O(n ²N⁴ +n³N³). In no case tested does the pseudospectral energy differ by more than 0.35 mhartree from the conventional result.
