MedeA Gaussian GUI: Expanding the Limits of Computational Chemistry


MedeA ®[1] Gaussian GUI provides a graphical user interface to the quantum chemistry code Gaussian. Gaussian is the software of reference for the quantum chemist. It includes the widest range of quantum chemical methods, including most of the known semi-empirical, DFT, time-dependent, Hartree-Fock, and post-Hartree-Fock methods, as well as a large library of electronic basis sets.

Key Benefits

  • Saves company R&D budget by speeding up research
  • Efficient GUI gives access to Gaussian
  • Fully integrates in the MedeA Environment
  • Benefits from all MedeA functionalities (High Throughput, etc.)
  • Offers the widest range of quantum chemical methods and computed molecular properties
  • Offers access to the gold standard of molecular properties from high level quantum chemistry
