It aims to be scalable both in its ability to treat large problems efficiently, and in its usage of available parallel computing resources

  • Q-Chem program exploits the latest developments in computer science, having adopted an Object Oriented approach to program design, which has been made possible by constructing a completely new program from the ground up.

  • Dalton is a powerful molecular electronic structure program, with an extensive functional for the calculation of molecular properties at the HF, DFT, MCSCF, and CC levels of theory

  • Psi 2.0 is a quantum chemistry program package developed by the Schaefer group. It is capable of evaluating SCF, MCSCF, CI, CCSD, and CCSD(T) energies and analytical gradients using expansions over Gaussian type basis functions

  • deMon program allows to perform DFT calculations on large systems including transition metals with precision in a relatively short time

  • HyperChem - Computational methods include molecular mechanics, molecular dynamics, and semi-empirical and ab-initio molecular orbital methods. HyperChem Data and HyperNMR have been migrated into HyperChem, and new features have been added. The new features include Open GL Rendering, DFT, TNDO, Charmm Protein Simulations, Molecules in Magnetic Fields, and much more.

  • Jaguar is a high-performance ab initio package for both gas and solution phase simulations, with particular strength in treating metal containing systems, making it the most practical quantum mechanical tool for solving real-world problems.

  • Spartan is a potent software tool that applies the power of molecular mechanics and quantum chemical calculations on your chemistry research. With state-of-the-art visualization and sophisticated computational algorithms, Spartan provides pharmaceutical and biotechnology organizations with key data supporting target identification and validation, lead selection and optimization, and process development.

  • ArgusLab - a freely licensed molecular modeling, graphics, and drug design program. Gaussian 98 & Gaussian 03 interfaces: easily set up and run Gaussian calculations on your local Windows PC. Outputs, surfaces plots, etc. are automatically added to the Calculation results in the Molecule Treeview. ArgusLab wraps the Gaussian calculation so effectively, you'll think it's a part of ArgusLab itself. You can also save ArgusLab-generated input files to run Gaussian offline or on another machine.

  • CASTEP is a software package which uses density functional theory to provide a good atomic-level description of all manner of materials and molecules. CASTEP can give information about total energies, forces and stresses on an atomic system, as well as calculating optimum geometries, band structures, optical spectra, phonon spectra and much more. It can also perform molecular dynamics simulations.

  • Insight II is a sophisticated molecular modeling environment that provides a powerful graphical interface to best-of-breed algorithms for molecular dynamics, homology modeling, de novo design, and electrostatics-making it the perfect solution for protein modelers, computational chemists, and structural biologists.

An industry standard for over 20 years and the basis for Tripos' expert molecular modeling environment, SYBYL provides the fundamental components for understanding molecular structure and properties with an emphasis on the discovery of lead candidates

  • Priroda 04 is a quantum-chemical program suite created by by D. N. Laikov designed for the study of complex molecular systems by the density functional theory, at the MP2, MP3, and MP4 levels of multiparticle perturbation theory, and by the coupled-cluster single and double excitations method (CCSD) with the application of parallel computing.

  • DGauss is a high-accuracy, high-performance computational chemistry package that uses density functional theory to predict molecular structures, properties and energetics.

  • PyQuante - Python Quantum Chemistry is an open-source suite of programs for developing quantum chemistry methods. The program is written in the Python programming language, but has many "rate-determining" modules also written in C for speed. The resulting code is not nearly as fast as Jaguar, Gaussian, or GAMESS, but the resulting code is much easier to understand and modify. The goal of this software is not necessarily to provide a working quantum chemistry program (although it will hopefully do that), but rather to provide a well-engineered set of tools so that scientists can construct their own quantum chemistry programs without going through the tedium of having to write every low-level routine.

  • Mopac 6 is the most widely distributed semiempirical quantum mechanics program in use throughout the world created by James JP Stewart

  • WinMopac is based on MOPAC, with addirional features and new methods, i.e. MNDO-d and PM5.

It is a modification of the original SINDO1 method. The current version of MSINDO includes parameters for the following elements: H, Li-F, Na-Cl, K-Br.

  • PyMOL is an open-source, user-sponsored, molecular visualization system created by Warren Lyford DeLano. It is well suited to producing high quality 3D images of small molecules and biological macromolecules such as proteins.
