The lecture will cover heteronuclear long-range correlation techniques like HMBC, H2BC, and HAT HMBC with the emphasis on determining the number of covalent bonds between two spins being correlated. H2BC and HMBC spectra are quite complementary as a peak can be strong in one of the two spectra and absent in the other. Editing according to the number of protons attached to the 13C spin is an additional useful feature simplifying and purging this type of spectra. Combining spectra with evolution under the coupling in the conventional and opposite sense, respectively, helps improve the editing accuracy and make new information visible. Bruker and Varian pulse programs for these experiments can be downloaded from http://www.crc.dk/nmr/.
