Determination of coupling constants by deconvolution of multiplets in NMR

Abstract:
The structures of multiplets in one- and two-dimensional NMR spectra can be simplified by recursive deconvolution in the frequency domain. Deconvolution procedures are described for in-phase and antiphase doublets of delta functions. Recursive simplification is illustrated by applications to double-quantum-filtered correlation spectra (DQF-COSY) and selective correlation spectra (soft-COSY). Coupling constants can be measured reliably even if signals of opposite signs lead to partial cancellation. Copyright 1999 Academic Press.

¹H NMR: Complex Splitting
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.
¹H NMR: Interpreting Distorted and Overlapping Signals
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...

Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must have a...
