ShelXle combines an editor with syntax highlighting for the SHELXL-associated .ins (input) and .res (output) files with an interactive graphical display for visualization of a three-dimensional structure including the electron density (Fo) and difference density (Fo-Fc) maps. See J. Appl. Cryst. (2011). 44, 1281–1284. for details.

The GNNPCSAFT Chat is an implementation of our project that focuses on using Graph Neural Networks (GNN) to estimate the pure-component parameters of the Equation of State PC-SAFT. We developed this app so the scientific community can access the model's results easily. In this app, you can chat with LLM models (Gemini or Ollama) with GNNPCSAFT tools, allowing you to ask questions about the PC-SAFT parameters of various compounds, predict thermodynamic properties, and get insights into the...

The GNNPCSAFT Web App is an implementation of our project that focuses on using Graph Neural Networks (GNN) to estimate the pure-component parameters of the Equation of State PC-SAFT. We developed this app so the scientific community can access the model's results easily. In this app, the estimated pure-component parameters can be used to calculate thermodynamic properties and compare them with experimental data from the ThermoML Archive. - CPU-compatible desktop build The standard...

...The program allows fast and easy building and/or editing different molecular structures, up to several thousands of atoms large. Luscus can also visualize dipole moments, normal modes, molecular orbitals, electron densities and electrostatic potentials. In addition, simple geometrical objects can be rendered in order to point out a geometrical feature or a physical quantity. The program is developed as a graphical interface for MOLCAS program package, however it's adaptive nature makes possible using luscus with other computational program packages and chemical formats. ...

ED Software project contains several programs used (mostly) for processing gas-phase electron diffraction (GED) experimental data.

JDFTx is a plane-wave density functional theory code designed for electronic structure theory development. One prominent unique capability is the treatment of solvated electronic systems using joint density functional theory. Please see http://jdftx.org for download and compile instructions, tutorials, documentation and citation information.

NESSIE is a modern first-principle calculation software that can adequately address the need for ever-higher levels of numerical accuracy and high-performance in large-scale electronic structure simulations, as well as pioneer the fundamental study of quantum many-body effects in a large number of emerging nanomaterials. NESSIE is an electronic structure code that uses a real-space FEM discretization and domain-decomposition (DD) to perform all-electron ground-state DFT and real-time excited-state TDDFT calculations. The code is written to take advantage of multilevel parallelisms of the FEAST eigenvalue solver to target systems containing many distributed-memory compute nodes. The real space mesh is generated using the software tetgen.

Olex2 is visualisation software for small-molecule crystallography developed at Durham University/EPSRC. It provides comprehensive tools for crystallographic model manipulation for the end user and an extensible development framework for programmers. The project has been supported by Olexsys Ltd since 2010.

Grid-based Coupled Electron and Electromagnetic field Dynamics (GCEED) is an open-source software package for massively parallel first-principles calculations of electron dynamics in real time and real space. The program codes are written in the Fortran 90/95 language with MPI and OpenMP. Time dependent density functional theory (TD-DFT) calculations can be performed on 100,000 CPU cores of K Computer with high parallel efficiency.

PLEASE NOTE ORBKIT HAS BEEN MOVED TO https://github.com/orbkit/orbkit orbkit is a parallel Python program package for post-processing wave function data extracted from output files of MOLPRO (Molden File Format), TURBOMOLE (AOMix file format), GAMESS-US, PROAIMS/AIMPAC (wfn/wfx file format), and Gaussian (Output File and Formatted Checkpoint File) output files. Futhermore, an interface to cclib, a parser for quantum chemical logfiles, is provided. If you use orbkit in your work,...

PLASMAKIN is a package to handle physical and chemical data used in plasma physics modeling and to compute gas-phase and gas-surface kinetics data: particle production and loss rates, photon emission spectra and energy exchange rates.

The Electron Pair Localization Function (EPLF) helps to understand chemical bonding in molecular systems. This code uses a modified formulation which allows the exact calculation of the EPLF for usual wave functions (HF,KS,CAS,...)

This is version 1.2 of "aufbau". Its purpose is to create electron configuration of an atom, molecule or ion, following, of course, the "Aufbau" Principle. You can subscribe to the project's mailing lit here: https://lists.sourceforge.net/lists/listinfo/atomic-aufbau-news

The Xtal System is a comprehensive suite of small molecule structural solution, refinement and analysis software, supporting both X-ray, neutron and electron diffraction data. It runs on both Unix and MS Win32 platforms and uses tcl/tk graphics.

Open-source Cube Files Manipulator Program (OpenCubMan)is a tool for computational chemists interested in performing operations on files with volumetric data representing wavefunctions or electron densities (often called cube files).

XD-shell - is a shell (console) interface to XD program which deals with experimental electron density refinement.

A multi-procedure, multi platform electron spectrum evaluation program, with special options for atomic physics and XPS/UPS spectroscopy.

gorbital is a atomic orbital viewer written using gtkmm (gtk--). gorbital displays a 3d interactive view of a electron orbitals. It is meant to be an open source viewer much like Orbital Viewer by David Manthey (http://www.orbitals.com/orb/).
