Correlation of 35c1 Nuclear-quadrupole Coupling Constants
From a consideration of odd-even intramolecular electron transfer processes in octahedrally co-ordinated transition metal complexes, two relationships have been derived. The first correlation describes 71 —> y3 optical electron transfer bands of the complexes K20sC l6 , K2IrCl6 , K2PtCl6 , K2PtCl4 as a function of the respective 35C1 nuclear quadrupole coupling constants. The second rela tions...
متن کاملDensity functional explorations of quadrupole coupling constants for BN, BP, AlN, and AlP graphene–like structures
Stabilizations and atomic level quadrupole coupling constant (CQ) properties have been investigated for graphene–like monolayers (G–monolayers) of boron nitride (BN), boron phosphide (BP), aluminum nitride (AlN), and aluminum phosphide (AlP) structures. To this aim, density functional theory (DFT) calculations have been performed to optimize the model structures and also to evaluate the CQ para...
متن کاملCollisional Damping of Giant Monopole and Quadrupole Resonances
Collisional damping widths of giant monopole and quadrupole excitations for Sn and Pb at zero and finite temperatures are calculated within ThomasFermi approximation by employing the microscopic in-medium cross-sections of Li and Machleidt and the phenomenological Skyrme and Gogny forces, and are compared with each other. The results for the collisional widths of giant monopole and quadrupole v...

متن کاملTemperature dependent deuterium quadrupole coupling constants of short hydrogen bonds
Very short hydrogen bonds universally show large positive dependences of the deuterium NMR quadrupolar coupling constant with temperature. We present temperature dependent NMR data for eight such systems, with O/O distances of between 238 and 250 pm, and show we can model the temperature dependences by density functional methods, as long as proper attention is paid to intermolecular effects and...
