Gaussian 16W is the Windows-native version of the industry-standard Gaussian electronic structure modeling software. Developed by Gaussian, Inc., it allows chemists, biochemists, materials scientists, and physicists to predict and model the properties of molecular systems from their desktop computers.
Are you looking to set up a specific type of calculation, like a or a TD-DFT frequency analysis? I can help you with the keyword syntax ! gaussian 16w
Allows users to easily create input files (using GaussView or the built-in editor), set calculation parameters, and manage job queues [Source: GV6 PDF ].
is the Windows-based version of the Gaussian 16 electronic structure modeling software. It is a powerful computational chemistry program used to predict the energies, molecular structures, and vibrational frequencies of molecular systems. Core Capabilities and Features

For users requiring accelerated calculations, Gaussian 16 supports for Hartree‑Fock and DFT calculations — but only under Linux . GPU support is not currently available in the Windows version of Gaussian 16. Supported GPU models include NVIDIA K40, K80, P100, and V100 with at least 12 GB of memory. Each GPU must be controlled by a specific CPU core.
The modern standard. It can utilize virtually unlimited RAM and disk space, allowing users to maximize the hardware capabilities of modern multi-core workstations. Recommended System Specifications
While the computational engine is identical, Gaussian 16W offers unique benefits for users on Windows: Gaussian 16W (Windows) Gaussian 16 (Linux/Unix) User-friendly GUI Command-line prompt Ease of Use High (Interactive) Moderate (Requires scripting) Parallelization Excellent (Multi-core) Excellent (Multi-node Clusters) Best For Desktop use, small-medium jobs HPC, heavy-duty production In default
Gaussian 16W can be used to study:
Gaussian 16w requires a Windows operating system (Windows 7, 8, or 10) and a compatible computer with a sufficient amount of RAM and disk space.
Calculating infrared (IR) and Raman spectra.
Configure the number of processor cores used. Common Issues and Troubleshooting
