Whether you are studying small organic molecules or large protein-ligand complexes, Revision C.01 provides the robust toolset necessary for modern computational workflows. Key Enhancements in Revision C.01
: Pushing the boundaries of spectroscopy modeling, Rev. C.01 included anharmonic vibrational analysis for Vibrational Circular Dichroism (VCD) and Raman Optical Activity (ROA) spectra with the Freq=Anharmonic keyword. It also added capabilities for computing vibronic spectra and intensities ( Freq=FCHT ) and resonance Raman spectra ( Freq=ReadFCHT ). For excited states, the Ciofini charge transfer diagnostic (keyword Pop=DCT ) was introduced to help characterize the nature of electronic transitions.
For researchers, the correct citation for this specific software version is:
Determining the minimum energy conformations of molecules, including transition states. If you want the primary source, the official
Molecular mechanics, semi-empirical, Hartree-Fock (HF), Density Functional Theory (DFT), Møller–Plesset perturbation theory (MP), and high-accuracy many-body methods (CC, CI).
When publishing results, Gaussian recommends citing the specific revision used—in this case, Gaussian 16, Revision C.01 .
While Gaussian 16 natively introduced long-range corrected functionals (like $\omega$B97X-D) and double-hybrid functionals, Rev. C.01 refines the integration grids and optimization routines for these methods. This reduces grid sensitivity and ensures that frequency calculations yield fewer spurious imaginary frequencies. Output and Interface Formatting
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. To maximize the value of Gaussian 16 Revision C
Updated, refined, or optimized algorithms for methods like TD-DFT, SCRF (Self-Consistent Reaction Field), and ONIOM, often leading to better convergence in tricky scenarios.
Here are some of the most noteworthy discussions regarding G16 C.01 available online:
Users upgrading to Revision C.01 from older versions (like Gaussian 09) will still benefit from the core Gaussian 16 advancements that this revision polishes:
Gaussian 16 (often abbreviated as G16) is a premier electronic structure software program designed to model molecular systems, spanning from small diatomic molecules to large biological systems, in both gas and condensed phases.
