Serial Number is valid working. Gaussian 16 is the latest in the Gaussian series of programs. It provides state-of-the-art capabilities for electronic structure modeling. Gaussian 16 is licensed for a wide variety of computer systems. All versions of Gaussian 16 contain every scientific/modeling feature, and none imposes any artificial limitations on calculations other than your computing resources and patience.

Gaussian 16 – Software Introduction

Gaussian 16 is a leading computational chemistry software package used by scientists worldwide to model the electronic structure and properties of molecules, materials, and chemical reactions. Developed by Gaussian, Inc., it provides advanced quantum mechanical methods for predicting molecular energies, structures, vibrational frequencies, reaction pathways, and spectroscopic properties.

It is widely used in academia, industry, and research institutions for applications in chemistry, materials science, biochemistry, nanotechnology, and pharmaceutical development.

Key Features of Gaussian 16

Quantum Chemistry Methods
- Supports a wide range of theoretical models:
  - Hartree-Fock (HF)
  - Density Functional Theory (DFT) – with numerous functionals (e.g., B3LYP, PBE, M06, ωB97X-D)
  - Møller-Plesset Perturbation Theory (MP2, MP4)
  - Coupled Cluster (CCSD, CCSD(T)) – “Gold standard” for accurate energy calculations
  - Semi-empirical methods (e.g., AM1, PM3, PM6, PM7)
  - Configuration Interaction (CIS, CISD) and Time-Dependent DFT (TD-DFT) for excited states

Molecular Properties & Analysis
- Calculates:
  - Molecular geometry optimization (including transition states)
  - Vibrational frequencies and IR/Raman spectra
  - NMR chemical shifts
  - Dipole and higher multipole moments
  - Electronic excitation energies (UV-Vis spectra)
  - Thermochemical data (enthalpy, entropy, heat capacity)
  - Reaction pathways and potential energy surfaces
Solvent Effects
- Includes implicit solvation models such as:
  - Polarizable Continuum Model (PCM)
  - SMD and CPCM
- Enables realistic simulation of reactions in solution.
Advanced Capabilities
- IRC (Intrinsic Reaction Coordinate) calculations to trace reaction mechanisms.
- Counterpoise correction for basis set superposition error (BSSE).
- Natural Bond Orbital (NBO) analysis for bonding insight.
- Fragment-based methods (e.g., Local MP2, ONIOM) for large systems.
High Performance & Scalability
- Parallelized for multi-core processors and clusters (supports shared and distributed memory).
- Efficient algorithms allow studies of medium to large molecules with high accuracy.
User Interface & Integration
- Gaussian 16 is command-line driven (input files in .gjf format), but can be used with graphical front-ends such as:
  - GaussView (official GUI for building molecules and visualizing results)
  - ChemCraft, Avogadro, Molden
- Output files (.log or .out) contain detailed results and can be analyzed visually or programmatically.
