Gaussian 03 for Windows (Size: 100 MB)
Gaussian 03 is the latest in the Gaussian series of electronic
structure programs. Gaussian 03 is used by chemists, chemical
engineers, biochemists, physicists and others for research in
established and emerging areas of chemical interest.
Starting from the basic laws of quantum mechanics, Gaussian predicts
the energies, molecular structures, and vibrational frequencies of
molecular systems, along with numerous molecular properties derived
from these basic computation types. It can be used to study
molecules and reactions under a wide range of conditions, including
both stable species and compounds which are difficult or impossible
to observe experimentally such as short-lived intermediates and
transition structures. This article introduces several of its new
and enhanced features.
