Improved Time-Dependent DFT (TD-DFT) gradients and analytic frequencies for excited state geometry optimizations.
If you are looking to deploy the new Windows version of Gaussian 16 on your workstation, this article details the official acquisition channels, system requirements, and step-by-step installation procedures. 1. Licensing and Official Download Channels
: At least 500MB for installation; significantly more for "Scratch" files during execution. ✨ New Features in Gaussian 16
Licenses are granted based on your institutional affiliation. Visit the official website of Gaussian, Inc. to explore licensing options: download+gaussian+16+windows+new
Ensure your license includes the latest revision (Rev C.02 as of late 2025). Older Rev A or B lack Windows-specific optimizations.
The phrase “download gaussian 16 windows new” should lead you to a licensed purchase portal, not a warez site.
Then edit the Path variable and add: C:\G16 Licensing and Official Download Channels : At least
These are not Gaussian, but for many tasks (geometry optimizations, vibration analysis), they are competitive and legally free.
: Choose the 64-bit Windows version (Rev. C.01 or the latest available maintenance release).
Create a new system variable named GAUSS_SCRDIR and point it to a fast, dedicated directory for temporary scratch files (e.g., C:\G16Scr ). Complementary Software: GaussView 6 to explore licensing options: Ensure your license includes
After installation, a icon will appear on your desktop. However, some initial configuration is required for optimal performance.
The default installation path is usually C:\G16W . It is highly recommended to keep this default path to prevent environment variable mapping issues later.
