Now Available: A New Parameterization of the DFT/CIS Method with Applications to X-ray Spectroscopy | |
Our latest Q-Chem webinar (Webinar 77), which was presented by Aniket Mandal on October 24, is now available! You can view the archived recording of the webinar here. Time-dependent density functional theory (TD-DFT) within a restricted excitation space is used as an efficient and reasonably accurate means to compute core-level spectra, using only a small subset of the occupied orbitals in what is known as the core/valence separation approximation. TD-DFT… Read More |
