Purchase a license from the official vendor (Gaussian, Inc.) or obtain it through your institution (university or company license).
Fortunately, the computational chemistry community has created an impressive array of free and open-source software that can serve as powerful and legitimate alternatives to Gaussian. Packages like ORCA, GAMESS, Psi4, NWChem, and CP2K offer state-of-the-art capabilities and are used by thousands of researchers worldwide. gaussian 16 software download free
However, many users can access Gaussian 16 at no personal cost through institutional affiliations. Below are the legitimate ways to obtain or use the software: 1. Institutional Site Licenses Purchase a license from the official vendor (Gaussian, Inc
Gaussian 16 is a premier commercial software suite for computational chemistry, used to model electronic structures and molecular properties . Because it is proprietary, there is no legitimate "free" download for personal use However, many users can access Gaussian 16 at
2. GAMESS (General Atomic and Molecular Electronic Structure System)
Red Hat Enterprise Linux (RHEL), CentOS, SUSE Linux Enterprise Server, and Ubuntu.
In summary, while Gaussian 16 is a powerful computational chemistry software, it's not available for free download. If you're interested in using the software, you'll need to purchase it or explore subscription-based options. Alternatively, you can consider free or open-source alternatives, which may offer similar functionality, albeit with some limitations.
