A significant addition within this NBO7 integration is the inclusion of the Pop=NEDA keyword. This command performs Natural Energy Decomposition Analysis (NEDA) using NBO7, which enables the decomposition of interaction energies into distinct physical components such as electrostatic, polarization, and charge transfer terms.
To get the most out of Gaussian 16 Revision C.01, computational scientists should structure their input files to exploit the revision's optimized defaults. Memory Allocation
Rev C.01 shows significantly better scalability above 16 cores due to improved Fock matrix construction and grid distribution.
Gaussian 16 Rev. C.01 addressed numerous bugs present in previous revisions. Additionally, for macOS users, the revision clarified compatibility issues: all 64-bit versions of Gaussian 16 work with macOS Catalina, but the 32-bit version (G16M) is not compatible because Catalina removed support for 32-bit applications. Site licenses covering macOS versions are all 64-bit and thus unaffected. gaussian 16 revision c.01
Gaussian 16 Revision C.01 is a maintenance and performance update for the Gaussian electronic structure modeling suite. This specific revision focuses on improving parallel efficiency and expanding hardware compatibility, particularly for High-Performance Computing (HPC) environments. Key Performance and Algorithm Improvements
Always specify memory allocations explicitly in your input files using the %Mem directive. For Revision C.01, giving the system adequate memory prevents costly disk-caching (paging), maximizing the benefits of the updated parallel algorithms. Conclusion
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. A significant addition within this NBO7 integration is
Gaussian 16 Revision C.01 maintains the high standard of accuracy required for publishing computational chemistry research. Its focus on efficiency in large system optimization and advanced spectral simulation makes it a reliable choice for research teams investigating everything from organic synthesis to complex inorganic materials.

Gaussian 16 Rev C.01 officially supports: Memory Allocation Rev C
: For researchers simulating molecular mechanics or dynamics, Rev. C.01 brought the ability to compute charges with a RESP (restrained electrostatic potential) constraint . Using a keyword like Pop=(MK,Resp=N) , users could add a restraint to charges derived from the electrostatic potential, a crucial step for generating accurate force field parameters. The revision also introduced Pop=SaveHirshfeld and Pop=SaveCM5 , allowing users to save these specific charge schemes for use in subsequent calculations.
Revision C.01 addresses several technical limitations found in earlier builds. The most notable updates include:
