Gaussian 16 Revision C.01 [upd] Jun 2026

: 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.

Revision C.01 expanded GPU support to include NVIDIA V100 (Volta architecture) cards, building upon previous support for K40, K80, and P100 cards introduced in Rev. B.01. For Linux systems, the x86_64 AVX-enabled binary version includes GPU support for NVIDIA K40, K80, P100, and V100 boards with 12 GB of memory or higher, requiring NVIDIA drivers compatible with CUDA 10.0.

If you are planning to configure an upcoming project or install this specific software version on your local machine or high-performance computing (HPC) cluster, I can provide tailored advice.

Gaussian 16 relies heavily on parallel computing to handle massive molecular systems. Revision C.01 optimizes shared-memory parallel execution (OMP) and network-parallel execution via Linda. gaussian 16 revision c.01

For modern quantum chemists, molecular modelers, and structural biochemists, Revision C.01 represents a shift from raw CPU dependency to modern, heterogeneous high-performance computing (HPC) environments. It addresses key limitations in memory management, multi-node scaling, and matrix data extraction for third-party developer integration. 🚀 Architectural Enhancements & Hardware Acceleration Native Support for NVIDIA Volta GPUs

%Mem and %NProcShared : Allocates 4 gigabytes of RAM and 4 CPU cores to the job.

In essence, Rev. C.02 was a maintenance and hardware support update. If you had an A100 GPU, you needed Rev. C.02. Otherwise, Rev. C.01 provided a richer and equally stable feature set. : Pushing the boundaries of spectroscopy modeling, Rev

Revision C.01 inherits and sharpens the core calculation shifts introduced in the base Gaussian 16 build over the aging Gaussian 09 framework. Gaussian jordan elimination method pdf

She fed the molecule into Gaussian the way a sculptor feeds stone to a blade—careful, deliberate, listening for the faintest voice. The first runs failed: oscillating geometries, near-degenerate states that refused to separate, messages that spoke of basis sets that were near the edge of sanity. The program’s output was an honest transcript of the molecule’s indecision: energies that swam, frequencies that flickered between real and imaginary. Mira adjusted, pruned, reconfigured. She iterated until the console’s green cursor was less a command prompt and more a heartbeat. For excited states, the Ciofini charge transfer diagnostic

: Utilities such as formchk gained a new -m command-line argument, allowing users to explicitly specify the memory available to the utility (e.g., formchk -m=1gb ). New Computational Features & Refinements

While Rev. C.01 was a feature-packed release, its successor, Rev. C.02, was much more targeted. The most substantial difference lies in the supported hardware:
