Application of the BIRD sandwich for the rapid and accurate determination of (1)H-(1)H NMR coupling constants in higher order spin systems.
A method is presented that allows for the convenient and reliable determination of (1)H-(1)H NMR coupling constants in higher order or symmetrically coupled spin systems. The method can be applied on any programmable FT-NMR spectrometer and is demonstrated here on micromole quantities of sample in a standard 5-mm NMR tube.
