Abstract
Simply successful: A proton-selective HSQMBC-TOCSY experiment can be used to measure small proton-carbon ( nJ CH; n>1) coupling constants on both protonated and non-protonated carbon atoms (see spectrum). 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 nJ CH can be determined simply with excellent accuracy. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
