The contact contribution to the nuclear spin-spin coupling constant in HD is evaluated variationally by using the nonsingular contact spatial part fm(r,a) =exp(-r/a)/2 a3, a=O (10-6) a.u. JHD is calculated to be 39 Hz and is independent of the sharp short-range part of the tri...

The INDOR technique has been applied to determine the sign of the coupling constant between protons in the ring position a in 4-aminopyridine and 4-chloropyridine which, contrary to the usual assumptions, were found to be positive, a result in agreement with the trend in other heterocyclic ...
Abstract Extensive ab initio MP2/aug’-cc-pVTZ studies have been carried out in our laboratories to determine the structures, binding energies, bonding properties, and EOM-CCSD spin-spin coupling constants of various series of complexes stabilized by pnicogen bonds. These systematic studies provide ...
This book describes spin-orbit coupling effects in quasi-two-dimensional electron and hole systems. The first part provides a general introduction to the electronic structure of quasi-two-dimensional systems with a particular focus on group-theoretical methods. The main part o...
Indirect nuclear spin–spin coupling constants calculated using restricted Hartree–Fock theory are unreliable since the usually dominant Fermi-contact (FC) contribution arises from a triplet perturbation of the electronic system, poorly described in the Hartree–Fock theory – in particular, at geometries...

Here we demonstrate a reciprocal effect of spin–orbit coupling when the direction of propagation of a surface plasmon wave, which intrinsically has unusual transverse spin, determines a scattering direction of spin-carrying photons. This spin–orbit coupling effect is an optical analogue of the spin...
demonstrating assembly-induced spin transfer. Besides, spin nanoparticles are found to couple and lose their paramagnetism at sufficiently short inter-nanoparticle distance, namely, the spin coupling depends on the inter-nanoparticle distance. However, it is not found that the spin coupling leads to th...
We study spin wave relaxation in quantum Hall ferromagnet regimes. Spin-orbit coupling is considered as a factor determining spin nonconservation, and external random potential as a cause of energy dissipation making spin-flip processes irreversible. We compare this relaxation mechanism with other relaxa...
