By choosing to use Gaussian 09 legitimately, researchers can:
The tale of the "Gaussian 09 crack" is a notorious chapter in the history of computational chemistry, though it is less about a software "crack" in the pirated sense and more about a controversial, deep-seated "crack" in the scientific community’s relationship with its creator, . The Ethics of Software and Science
Because Gaussian is expensive and restricted, the search for a "crack" often takes two forms in student lore:
Based on the analysis presented in this article, we recommend the following:
