Exploring Gaussian 16 Revision C.01: What’s New and Why It Matters Since its release, Gaussian 16
Ensure you use AVX2-enabled platforms to leverage GPU support, specifically for NVIDIA boards with at least 12 GB of memory.
Revision C.01 brings major analytical power to excited state investigations. The inclusion of analytic second derivatives for Time-Dependent Density Functional Theory (TD-DFT) enables the prediction of vibrational frequencies, IR and Raman spectra for excited states, as well as performing transition state optimizations and IRC (Intrinsic Reaction Coordinate) calculations. Furthermore, analytic gradients for EOMCC (Equation-of-Motion Coupled Cluster) allow for geometry optimizations of excited states with high-level correlation methods.
For multi-scale modeling, the Revision adds more detail to the matrix element file for ONIOM (Our own N-layered Integrated molecular Orbital and molecular Mechanics) calculations. It now includes more comprehensive information about ONIOM layers, optimization steps, and trajectory results, improving the utility and transparency of these hybrid calculations. gaussian 16 revision c.01
Whether you are studying small organic molecules or large catalytic complexes, this revision provides the reliability needed for high-impact peer-reviewed research.
: In terms of performance, the most significant hardware addition was official support for NVIDIA V100 GPUs (Volta architecture) for Hartree-Fock and DFT calculations under Linux. This built on the support for older P100 GPUs introduced in Rev. B.01.
Gaussian 16 Revision C.01 is the definitive release of the Gaussian 16 quantum chemistry software suite, offering an unparalleled combination of advanced methodologies, enhanced performance through GPU and parallel computing, and the stability of a mature software product. The expansion of NBO7 and energy decomposition analysis, the addition of new density functionals, and major advancements in excited-state chemistry analysis make it a powerful tool for a diverse range of scientific inquiries.
