Erratum: Analysis of isotope effects in NMR one-bond indirect nuclear spin-spin coupling constants in terms of localized molecular orbitals
(Royal Society Of Chemistry, 2010-12)
The numerical values given for the reduced coupling constants, KX–H (in 1018 J 1 T2 ), and for the changes in the reduced coupling constants, DKX–H (in 1018 J 1 T2 ), in Tables 2 to 7 and Figures 1 to 4 have to be multiplied ...
Large long-range F-F indirect spin-spin coupling constants. Prediction of measurable F-F couplings over a few nanometers
(American Chemical Society, 2004-05)
Large long-range indirect nuclear spin coupling constants are of great interest for quantum computers. But they are rarely observed and are usually considered very small, unless the coupled nuclear spins are proximate in ...
The influence of relativistic effects on nuclear magnetic resonance spin–spin coupling constant polarizabilities of H2O2, H2S2, H2Se2, and H2Te2
(John Wiley & Sons Inc, 2018-12)
Relativistic and nonrelativistic calculations have been performed on hydrogen peroxide, dihydrogen disulfide, dihydrogen diselenide, and dihydrogen ditelluride, H2X2 (X = O, S, Se, Te), to investigate the consequences of ...
Optimized basis sets for the calculation of indirect nuclear spin-spin coupling constants involving the atoms B, Al, Si, P, and Cl
(American Institute Of Physics, 2010-08)
The aug-cc-pVTZ-J series of basis sets for indirect nuclear spin-spin coupling constants has been extended to the atoms B, Al, Si, P, and Cl. The basis sets were obtained according to the scheme previously described by ...
Unexpected geometrical effects on paramagnetic spin-orbit and spin-dipolar 2 J FF couplings
(American Chemical Society, 2012-05)
The second-rank tensor character of the paramagnetic spin-orbit and spin-dipolar contributions to nuclear spin-spin coupling constants is usually ignored when NMR measurements are carried out in the isotropic phase. However, ...
Indirect nuclear spin-spin coupling constants and chemical shifts in norbornene- derivatives bearing boronic acid pinacol ester group
(Research Trends, 2021-11-02)
We have simulated the nuclear magnetic resonance (NMR) parameters of ten norbornene-derivativesbearing a boronic acid pinacol ester group. In particular, we have calculated the 13C and 1H chemicalshifts and proton-proton ...
RPA(D) and HRPA(D): Two new models for calculations of NMR indirect nuclear spin–spin coupling constants
(John Wiley & Sons Inc, 2018-12)
In this article, the RPA(D) and HRPA(D) models for the calculation of linear response functions are presented. The performance of the new RPA(D) and HRPA(D) models is compared to the performance of the established RPA, ...
Analysis of isotope effects in NMR one-bond indirect nuclear spin-spin coupling constants in terms of localized molecular orbitals
(Royal Society Of Chemistry, 2009-03)
We recently showed, by analyzing contributions from localized molecular orbitals, that the anomalous deuterium isotope effect in the one-bond indirect nuclear spin–spin coupling constant of methane, also called the unexpected ...
The Anomalous Deuterium Isotope Effect in the NMR Spectrum of Methane: An Analysis in Localized Molecular Orbitals
(Wiley VCH Verlag, 2008-06)
Anomaly explained: The secondary isotope effect on the carbon–hydrogen indirect nuclear spin–spin coupling constant in methane, which is larger than the primary isotope effect, is explained in terms of contributions to the ...
The use of locally dense basis sets in the calculation of indirect nuclear spin–spin coupling constants: The vicinal coupling constants in H3C–CH2X (X=H, F, Cl, Br, I)
(American Institute of Physics, 2000-03)
We have calculated the vicinal indirect nuclear spin-spin coupling constants 3J1H1H3J1H1H in the series of molecules H3C–CH2XH3C–CH2X with X=H, F, Cl, Br, and I at the self-consistent field level and using the second order ...
