Gaussian Interface

Quantum Mechanical Computational Chemistry

Gaussian 16 is the latest version of the Gaussian series of electronic structure programs, used by chemists, chemical engineers, biochemists, physicists and other scientists worldwide.

Starting from the fundamental laws of quantum mechanics, Gaussian 16 predicts the energies, molecular structures, vibrational frequencies and molecular properties of compounds and reactions in a wide variety of chemical environments.

ĤΨ = EΨ

Based on the Schrödinger equation, Gaussian provides accurate predictions of molecular properties, enabling researchers to study chemical systems that are difficult or impossible to investigate experimentally. The program implements a wide range of quantum chemical methods, from basic semi-empirical calculations to sophisticated correlated methods.

With Gaussian, researchers can model chemical reactions, predict spectroscopic properties, study excited states, calculate thermochemical properties, and investigate many other chemical phenomena. The software is continuously updated with the latest methodological advances, ensuring that users have access to state-of-the-art computational tools.
