, M. J. Frisch et al., Gaussian, Inc., Wallingford CT, 2016. Key Technical Details for Revision C.01
: Time-Dependent Density Functional Theory (TD-DFT) analytical gradients and frequencies receive stability updates, specifically for systems using large basis sets with diffuse functions. gaussian 16 revision c.01
Based on your query, "" refers to a specific version of the Gaussian software package. Key Technical Details for Revision C
Improved robustness when using the Polarizable Continuum Model (PCM) alongside complex multi-reference methods. 2. Optimized Parallel Processing (Shared Memory & Linda) a 64-bit processor
Be aware that Gaussian 16 uses UltraFine as the default DFT grid and an integral accuracy of 10^-12 , which are higher than previous generations like Gaussian 09. If you are setting up a new workflow, I can help you: Identify the correct GPU hardware for your budget
As of 2025, Gaussian Inc. has not announced a formal "Gaussian 17" or "Gaussian 20". Instead, they have iterated on the Gaussian 16 codebase with revisions C.02, C.03, and D.01 (a minor update for Apple Silicon). However, remains the last version with extensive HPC testing and widespread community validation.
The software requires a minimum of 8 GB RAM, a 64-bit processor, and a compatible graphics card. For more information on system requirements and purchasing options, visit the Gaussian, Inc. website.
