16 Μαρ 2023 · To consider what happens in the process of fluorescence, we need to think of the possible energy states for a ground and excited state system. Draw an energy level diagram for a typical organic compound with \(\pi\) and \(\pi\) * orbitals.
8 Αυγ 2018 · The competition between these processes determines the fate of an electronically excited system—some emit light back, some effectively convert excess electronic energy into heat, some produce charge carriers, and some change their chemical identity.
These properties include the fundamental gap and its renormalization, hybridization and band dispersion, singlet and triplet excitations, optical spectra, and excitonic properties. For each, we present concrete examples, a comparison to experiments, and a critical discussion.
1 Ιαν 2011 · Central to any understanding of photochemistry is the concept that molecular systems possess well-defined electronic states: ordinary (thermal) chemistry is the chemistry of the ground electronic state, while photochemistry is the chemistry of (or originating from) electronic excited states.
1 Ιαν 2014 · In anionic systems, new types of excited states are present, such as the resonance states or the multipole-bound (dipole, basically) states, where the bonding energy is the result of the interaction between the additional electron and the multipole moments of the molecule.
1 Δεκ 2003 · Excited-state properties such as linear optical properties, magneto-optical properties, XANES, XPS, UPS, BIS, and Raman spectra can be obtained from accurate DFT calculations.
23 Νοε 2020 · An excellent reference for both researchers and students, Excited States provides essential knowledge on quantum chemistry, an in-depth overview of the latest developments, and theoretical techniques around the properties and nonadiabatic dynamics of chemical systems.
