Software for the frontiers of quantum chemistry: An overview of developments in the Q-Chem 5 package. [J. Chem. Phys.. 155, 084801 (2021)]
Literature citations for Q-Chem v. 2.0585, v. 3.01020, and v. 4.01021 are also available, and the most current list of Q-Chem authors can always be found on the website, www.q-chem.com. The primary literature is extensively referenced throughout this manual, and users are urged to cite the original literature for particular theoretical methods. This is how our large community of academic developers gets credit for its effort.
