What Does NDDO Stand For?

NDDO stands for Neglect Of Diatomic Differential Overlap

NDDO, or Neglect Of Diatomic Differential Overlap, is a computational chemistry approach used to simplify the calculation of electronic structures in molecular systems. By approximating the overlap integrals between atomic orbitals, NDDO enables the efficient assessment of molecular properties while maintaining a balance between accuracy and computational feasibility. This method is particularly valuable in the study of larger molecules where traditional approaches may be computationally prohibitive.
