What Does NNDO Stand For?

NNDO stands for Neglect Of Nonbonded Differential Overlap

NNDO, or Neglect Of Nonbonded Differential Overlap, is a quantum mechanical approximation used in computational chemistry. It simplifies the calculation of molecular interactions by neglecting the differential overlap of nonbonded electron pairs, thus streamlining the evaluation of electronic structure in large molecular systems. This approach helps in reducing computational complexity while maintaining a reasonable accuracy for predicting molecular properties and behaviors.
