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 ...

Combining the power of J coupling and DP4 analysis on stereochemical assignments: the J -DP4 methods
(American Chemical Society, 2019-05-24)
A systematic study to include 3JHH couplings into DP4 formalism (J-DP4) led to the development of three alternative strategies. The dJ-DP4 (direct) approach involves a new DP4-like equation including an additional probability ...
