What Does PNDO Stand For?

PNDO stands for Partial Neglect Of Differential Overlap

PNDO, or Partial Neglect Of Differential Overlap, is a computational method used in quantum chemistry and materials science to simplify the calculations of electronic structures. It approximates the interactions between electrons in complex systems by neglecting certain differential overlap contributions, thereby streamlining the analysis while maintaining sufficient accuracy for many applications. PNDO is particularly useful in large molecular systems where full electron correlation calculations would be computationally prohibitive.
