Chemistry Software Programs

College faculty have been leaders at the frontiers of knowledge since 1872. Current pioneering research includes premier programs in catalysis, thermodynamics, chemical biology, atmospheric chemistry, the development of polymer, optical and semiconductor materials, and nanoscience, among others. Jul 18, 2011 Annotated guide to free chemistry software (chemical freeware), intended for students and faculty who need high quality, specialized software for chemical structure drawing and 3D viewing, information on elemental or molecular properties, equilibrium calculations, etc.

Quantum chemistry computer programs are used in computational chemistry to implement the methods of quantum chemistry. Most include the Hartree–Fock (HF) and some post-Hartree–Fock methods. They may also include density functional theory (DFT), molecular mechanics or semi-empirical quantum chemistry methods. The programs include both open source and commercial software. Most of them are large, often containing several separate programs, and have been developed over many years.

The following table illustrates the capabilities of the most versatile software packages that show an entry in two or more columns of the table.

Jul 24, 2019 We ranked the best chemistry programs in the world based on academic rigor and faculty influence in chemistry and identified most important characteristics of each of the top 50 chemistry programs, revealing why each university chemistry program appears where it does. Here is a list of best free Chemistry Simulation Software for Windows. These free Chemistry simulation software let you learn the molecular models of different compounds. You can also learn how chemical reactions take place. The 3D molecular structures of different chemical compounds help to learn concepts of Chemistry easily. Chemical Software Find the best Chemical Software for your business. Learn more about HSC Chemistry. Essential software toolkit for mineral processing professionals for process research, development, and analysis. Software for Chemical companies helps establish best-in-class operational risk management and product stewardship programs. Chemistry Freeware Links. On this page I post reviews and links to freeware chemistry programs available for download at other sites around the internet. All of the programs are ones that I have used, or currently use. None-the-less, I take no responsiblity for any problems you might experience as a result of installing any of these applications.

^† 'Academic': academic (no cost) license possible upon request; 'Commercial': commercially distributed.

^‡ Support for periodic systems (3d-crystals, 2d-slabs, 1d-rods and isolated molecules): 3d-periodic codes always allow simulating systems with lower dimensionality within a supercell. Specified here is the ability for simulating within lower periodicity.

¹ The CAMPOS project(which includes Dacapo) states that all code is GPL. The Dacapo distribution contains no license information.

² QuanPol is a full spectrum and seamless (HF, MCSCF, GVB, MP2, DFT, TDDFT, CHARMM, AMBER, OPLSAA) QM/MM package integrated in GAMESS-US.^[3]

³ Through Ascalaph

⁴ Through interface to MOPAC

⁵ Using exact exchange DFT

⁶ Distributed with Quantum ESPRESSO

⁹Atomistix ToolKit also contains finite-bias NEGF electron transport calculations with open boundary conditions.

¹⁰ Through CRYSCOR program.

¹¹ However, available in the Schrödinger Suite.

¹²SIESTA also contains finite-bias NEGF electron transport calculations with open boundary conditions using TranSIESTA.
