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 coupling constants for an electroweak model with an SU(4)(PS) circle times SU(4)(EW) unification symmetry
(International Academic Publishers LimitedHong KongChina, 2007)
The strong coupling constant

On the angular dependence of the vicinal fluorine-fluorine coupling constant in 1,2-difluoroethane: deviation from a karplus-like shape
(American Chemical Society, 2006-06)
The angular dependence of the vicinal fluorine−fluorine coupling constant, 3JFF, for 1,2-difluoroethane has been investigated with several polarization propagator methods. 3JFF and its four Ramsey contributions were ...
Phenomenological tests for the freezing of the QCD running coupling constant
We discuss phenomenological tests for the frozen infrared behavior of the running coupling constant and gluon propagators found in some solutions of Schwinger-Dyson equations of the gluonic sector of QCD. We verify that ...
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 ...
Stereochemical dependence of NMR geminal spin-spin coupling constants
(John Wiley & Sons Ltd, 2008-12)
In this work it was sought to explore the versatility of germinal spin–spin coupling constants, ²JxySSCCs, as probes for stereochemical studies. A set of compounds, where their experimental ²JxySSCCs through the X–C–Y ...
Stereochemical behavior of (1)J(CH) and (2)J(CH) NMR coupling constants in alpha-substituted acetamides
(Elsevier Science BvAmsterdamHolanda, 2008)
NMR spin-spin coupling constants and hyperconjugative interactions
(John Wiley & Sons Inc, 2010-06)
The potential of NMR spin-spin coupling constants as probes to study fine details of electronic molecular structures is briefly discussed in this work through two different examples. A qualitative analysis of the polarization ...
A computational study of ² JHH(gem) indirect spin-spin coupling constants in simple hydrides of the second and third periods
(John Wiley & Sons Ltd, 2008-02)
Several theoretical methods have been used to compute ²JHH in neutral, anionic and cationic HXH hydrides, X being the 14 nuclei from Li to CI (28molecules). Since the calculations also provide ¹JXH spin‐spin coupling ...
