WebAssignment of heteronuclear spectra: Similarly, the above method of sequential assignment can be used to assign heteronuclear 3D spectra such as 15 N NOESY-HSQC and 15 N TOCSY-HSQC, because in each 15 N plane of such a spectrum only the NOESY or TOCSY signals from that proton are visible which is directly attached to the regarded nitrogen …
