title: A definitive NMR solution for a simple and accurate measurement of the magnitude and the sign of small heteronuclear coupling constants on protonated and non-protonated carbon atoms.
abstract: Simply successful: a proton-selective HSQMBC-TOCSY experiment can be used to measure small proton-carbon ((n)J(CH); n>1) coupling constants on both protonated and non-protonated carbon atoms. The method combines in a single pulse scheme all the benefits of the widely used HSQMBC and HSQC-TOCSY experiments. The magnitude and the sign of (n)J(CH) can be determined simply with excellent accuracy.
