Online quantum chemistry textbook written by C. David Sherrill, School of Chemistry and Biochemistry, Georgia Institute of Technology. It was created as part of a resource for college students at both the undergraduate and post-graduate levels. This textbook has been adopted by colleges around the world and has also helped more than a few high school students get a head start on their classmates.
