Let us now compare the Coulomb contribution to the electronic coupling in environment and in vacuum with the total electronic coupling (see figures 2(b) and (c), respectively). Neglecting the explicit contribution (like in figure 2 (b)) results in large errors on the coupling value, up to 100 cm −1 for the largest couplings.The calculations demonstrate the concept of enhancing the electronic coupling, and hence the stability, by exploring the stabilizing features of CH3PH3+, CH3SH2+, and SH3+ cations, among several ...Electron-phonon coupling (EPC) in bulk materials is an important effect in multifarious physical and chemical phenomena. It is the key to explaining the mechanisms for superconductivity, electronic transport, etc. The EPC matrix describes the coupling of the electronic eigenstates of the studied system under the perturbation of phonons. …

In this study, nickel-iron sulfide (NiFeS) nanosheets were immobilized on Ti 3 C 2 MXene-decorated nickel foam (Ti 3 C 2 MXene/NF) by hydrothermal reaction (NiFeS@Ti 3 C 2 MXene/NF).

Hollywood relationships that last tend to be few and far between, but there are also more than a few that might make you want to find your soulmate and love the heck out of them. Will Smith and Jada Pinkett Smith have one of the strongest m...Sep 15, 2021 · Electronic coupling (also called excitonic coupling) between molecules of the same species is known to induce two bands of opposite sign (biphasic bands) in CD spectra, and this phenomenon is called exciton-coupled CD (ECCD) (Harada and Nakanishi, 1983; Berova et al., 2000). This interaction is called the "electronic coupling" between the orbitals and has units of energy. In the Hückel approximation this energy is the same for all carbon p-orbitals that are adjacent to on another and is called β. Non- Adjacent p orbitals do not interact. For atoms that are not adjacent to one another β is taken to be zero. ….

In the limit of strong electron–phonon coupling and weak intermolecular electronic coupling, a charged molecule undergoes a large geometry relaxation, which eventually traps the charge. In this case, the charge transport can be viewed as an intermolecular hopping process. With the known electron transfer rates …
