Thanks for taking the time to read this!

We use automatic differentiation to provide arbitrary order derivatives from an implementation of the exchange-correlation energy. Therefore this library is very easy to use for development of new functionals, as well as using existing functionals for various kinds of perturbation theory. The library is free software, and we have already implemented many of the popular functionals. External contributions are very welcome! If it sounds interesting you may have a look at our recent JCTC publication "Arbitrary-Order Density Functional Response Theory > from Automatic Differentiation" U. Ekstr=F6m, L. Visscher, R. Bast, A.J. Thorvaldsen and Kenneth Ruud May 24, 2010 DOI: 10.1021/ct100117s or the project website (with links for source code download): http://admol.org/xcfun Sincerely, Ulf Ekstr=F6m
