Spartan

Spartan is a molecular modeling and computational chemistry software developed by Wavefunction, Inc., used to predict the structures, properties, and reactivity of molecules.

Platforms

Windows Mac Linux

 Spartan is a computational chemistry program from Wavefunction, widely used in academia for instruction and research across disciplines. Spartan has the best graphical user interface for the “building” of molecular structures, including complex biomolecules and weakly bound aggregates, and greatly simplifies the setup, execution, and analysis of calculations. Spartan implements a wide variety of modern computational methods, including semi-empirical, Hartree-Fock, and DFT methods, for ground and excited state species as well as transition states. All methods beyond molecular mechanics and semi-empirical utilize the latest Q-Chem computational engines.

It can use multiple cores (up to 16 cores; please inquire if you need more). It also incorporates extremely powerful visualization tools to represent molecular orbitals, vibrational modes, electrostatic potentials, and calculated spectra and energy levels. Spartan is also compatible with several other common computational chemistry file formats (e.g., .cif, .smi, .mol, .mol2). 

Spartan '24 is no longer supported; you must upgrade to Spartan '26. The ITS license server supports Spartan '26. Please follow the download and installation steps provided below.
