Diabatic coupling
WebWhen dealing with multiple charge or electronic excitation centers, diabatic states can be constructed with Boys 932 or Edmiston-Ruedenberg 928 localization. In this case, we construct diabatic states as linear combinations of adiabatic states with a general rotation matrix that is in size: (10.73) WebJan 12, 2024 · Block-Localized Excitation for Excimer Complex and Diabatic Coupling Block-Localized Excitation for Excimer Complex and Diabatic Coupling J Chem Theory …

WebNov 16, 2010 · Recently, we have proposed a scheme for the calculation of nonadiabatic couplings and nonadiabatic coupling vectors within linear response time-dependent density functional theory using a set of auxiliary many-electron wavefunctions [I. Tavernelli, E. Tapavicza, and U. Rothlisberger, J. Chem. Phys. 130, 124107 (2009)].
WebDec 1, 2001 · The mechanisms responsible for the influence of diabatic heating on TC motion and vertical coupling have been primarily explained in terms of the asymmetric flow induced by diabatic heating, a concept originally established from barotropic TC motion ( Fiorino and Elsberry 1989 ). WebAdiabatic electron-transfer is a type of oxidation-reduction processes. The mechanism is ubiquitous in nature in both the inorganic and biological spheres. Adiabatic electron-transfers proceed without making or breaking chemical bonds. Adiabatic electron-transfer can occur by either optical or thermal mechanisms.
WebThe direct coupling (DC) scheme calculates the electronic coupling values via Eq. (10.85), and it is widely used to calculate charge transfer coupling. 707, 104, 251, 1098 In the DC scheme, the coupling matrix element is calculated directly using charge-localized determinants (the “diabatic states” in electron transfer literature).In electron transfer … WebApr 9, 2024 · The adiabatic and diabatic representations are formally equivalent, however, the derivative couplings (A n m) which appear in the adiabatic Hamiltonian are singular at the CI. These singularities are very difficult to treat numerically, so the smooth non-singular diabatic Hamiltonian is used instead.
WebMar 1, 2024 · We study nonadiabatic coupling in systems of weakly interacting open-shell molecules which have nearly degenerate electronic states and hence significant nuclear derivative couplings. By comparison to numerically calculated nuclear derivatives of adiabatic electronic wave functions, we show that nonadiabatic couplings are …
