PROMOLDEN

About

PROMOLDEN is our in-house code for the topological analysis of scalar fields derived from the electron density and pair density. It implements:

  • QTAIM basin integration — atomic charges, volumes, and energies from IQA.
  • IQA energy decomposition — intra-atomic self-energies and inter-atomic electrostatic/exchange–correlation interactions.
  • Delocalization and localisation indices — bond orders from the electron pair density.
  • Non-covalent interaction (NCI) index — identification and visualisation of van der Waals, hydrogen bond, and steric interaction regions.
  • Electron localisation function (ELF) — topological analysis of electron pairing.

Availability

PROMOLDEN is available for academic use upon request to the PI. Please contact ampendas@uniovi.es to obtain the code and documentation.
