Small Molecule Repository
 
 

Small Molecule Repository

The collection of small molecules presented here were initially for the use of High School teachers that participated in the inaugural "No Teacher Left Behind" computational chemistry course offered in the Summer of 2004. The Small Molecule Repository was started after the teachers had used Spartan and wanted to be able to show their students the concepts discussed as a class. The molecules presented below are available in several file formats with their geometries optimized using Gaussian with the noted level of theory. To view the Gaussian output it is best to use gOpenMol or Molekel as described by Jeremy Beck and Rachel Fogle of York College of Pennsylvania (this link: http://educ.gaussian.com/visual/index.html).

Those interested in have additional small molecules added to the repository, please email us with your suggestions and we will post them within 2 weeks. Email your desired compound to the Departmental Email Account. We ask that you send a drawn structure and the class you intend to use it in.

Please check back periodically for new and updated structures.
Thank you.
