AtomDB is a versatile, free, and open-source Python library for accessing and managing atomic and promolecular properties. It serves as an extended database or periodic table of neutral and charged atomic properties, offering accurate experimental and computational data for various atomic charge/multiplicity states. AtomDB is a QC-Devs project.
AtomDB's documentation, including installation and usage instructions, as well as API documentation, is available at atomdb.qcdevs.org.
-
Atomic scalar properties
AtomDB provides a wide range of atomic properties for neutral and charged atoms, including: Atomic number, Atomic symbol, Atomic mass, Atomic radius, van der Waals radius, Covalent radius, Ionization potential, Electron affinity, Electronegativity, Atomic polarizability.
-
Point dependent properties
AtomDB provides functions to calculate point-dependent properties, such as: Electron density
$\rho(r)$ , Electron density gradient$\nabla \rho(r)$ , Electron density Laplacian$\nabla^2 \rho(r)$ , Electron density Hessian$\nabla^2 \rho(r)$ (for these properties, only the radial part is provided), and Kinetic energy density$ked(r)$ .The computation of contributions per orbital, set of orbitals, or spin to these properties is also supported.
-
Promolecular properties
AtomDB provides the capabilities to create promolecular models, and then estimate molecular properties from the atomic properties.
-
Dumping and loading
AtomDB provides the capability to dump and load atomic properties to and from JSON files.
For a complete list of available properties, see this table.
We recommend using Python 3.9 or later. The qc-grid is need to run AtomDB. You can install it
from source for now:
pip install git+https://github.com/theochem/grid.gitThen,
qc-AtomDB can be installed using pip:
pip install qc-AtomDB
