Gaussian 16 Revision C.01: A Comprehensive Review of the Latest Quantum Chemistry Software

Computational Details

All density functional theory (DFT) and ab initio calculations were performed using the Gaussian 16 software package, Revision C.01 [1]. Geometry optimizations and frequency calculations were carried out using the [insert functional, e.g., B3LYP] functional in conjunction with the [insert basis set, e.g., 6-31G(d)] basis set. Stationary points were characterized as minima (no imaginary frequencies) or transition states (one imaginary frequency) by vibrational analysis. Single-point energy calculations were refined using the [insert higher level method, e.g., M06-2X] functional and the [insert larger basis set, e.g., 6-311+G(d,p)] basis set. Solvent effects were modeled using the polarizable continuum model (PCM) [2] with [insert solvent, e.g., water] where applicable. All optimized structures were visualized using [insert visualization software, e.g., GaussView 6]. gaussian 16 revision c.01

The Gaussian software series has been around since the 1980s, with the first version being released in 1981. Developed by John M. Frisch and his team, the software was initially designed to perform quantum chemical calculations on small molecules. Over the years, the software has evolved significantly, with each new version bringing improved algorithms, new methods, and enhanced performance. Gaussian 16 Revision C

However, initial revisions contained bugs—some benign, others problematic for convergence or symmetry handling. Revision B.01 introduced patches and modest performance tweaks. Revision C.01 arrived as the most mature release of the 16 series before the eventual announcement of Gaussian 17/18 (note: Gaussian Inc. later released Gaussian 16 Rev C.01 as a stable endpoint, with Rev C.02 and C.03 addressing minor platform-specific issues).

There was a small applause, the sort that acknowledges not only the data but the process of discovering it. On her way out, someone from a different group—spectroscopists who had never before cared for the minutiae of basis sets—pulled her aside. They wanted to look for experimental signatures, to see whether the computed bridge-state had a real spectral fingerprint. The possibility that computation and experiment could meet in a particular corner of parameter space felt like a secret passage opening between two rooms of a house.
