TOPOND23

The new version of TOPOND is now available within the CRYSTAL23 package
The CRYSTAL Team is pleased to announce the release of TOPOND23, an indispensable tool for the topological analysis of electron density and its Laplacian through the instruments of the Quantum Theory of Atoms in Molecules and Crystals.
TOPOND23 most relevant new features are:

• Extension to the use of f- and g-types atomic orbitals.
  This opens up the possibility of studying the chemistry of f-electrons in complexes and compounds containing lanthanides and actinides. Here are the first exciting applications:
  1. Charge density analysis of actinide compounds from the quantum theory of atoms in molecules and crystals, J. Phys. Chem. Lett. 12, 1862, (2021).
  2. Topology of the Electron Density and of Its Laplacian from Periodic LCAO Calculations on f-Electron Materials: The Case of Cesium Uranyl Chloride, Molecules 26, 4227, (2021).
• New Python based tools for 2D visual analysis of the topological quantities, i.e. charge density, laplacian, trajectories, etc...
