We are grateful to Prof. Björn O. Roos and Dr. Per-Olof Widmark, University of Lund, for kindly allowing us to include in the distribution of the DALTON program routines for integral presorting (BOR), two-electron integral transformation routines (BOR) and routines for synchronous and asynchronous I/O (POW).
We are grateful to professor Knut Fægri (University of Oslo) who took the time to reoptimize the basis set of van Duijneveldt in order to provide in electronic form a basis set of similar performance to these widely used basis set, included here as the Not Quite van Duijneveldt (NQvD) basis sets.
We would also like to express our gratitude to Andreas Hesselmann (University of Düsseldorf), Gilbert Hangartner (University of Freiburg), and Antonio Rizzo (Istituto di Chimica Quantistica ed Energetica Molecolare del CNR, Pisa) for allowing us to distribute their utility programs for pre- and post-processing of DALTON input/output-files, as described in the Appendix.
A long list of users, too long to mention here, is thanked for an enormous amount of valuable feedback on the performance of the code. Without their assistance, the code would not have looked the way it does now.
