What Does PNDDO Stand For?

PNDDO stands for Partial Neglect Of Diatomic Differential Overlap

PNDDO, or Partial Neglect Of Diatomic Differential Overlap, is a computational chemistry method that simplifies the analysis of molecular interactions by neglecting certain overlap integrals in diatomic systems. This approach allows for efficient calculations of electronic structures and properties by focusing on the dominant contributions while minimizing computational complexity, making it suitable for large molecular systems where full ab initio methods would be computationally prohibitive. PNDDO is particularly useful in studying molecular bonding and reactivity in various chemical environments.
