We have just received the latest version of the popular computational chemistry software Gaussian 16. This is a major update. It’s so new, Gaussian has not quite caught up with it on their website at http://gaussian.com. Please read through our help file http://cac.queensu.ca/wiki/index.php/HowTo:gaussian to learn about new features and how to use the software on our systems. If you are already a Gaussian user, the switch is easy: replace the setup command “use g09” by “use g16”. Done.
