A spin system of an unknown compound from an E. coli cell lysate extracted from the 3D HSQC-TOCSY and verified by 2D TOCSY (and 2D HSQC-TOCSY). (A) Cross-peaks of the unknown compound shown in the 2D HSQC (blue cross-peaks) and 2D TOCSY (blue and red cross-peaks) spectra. (B) Two of the top scoring compounds matching the unknown spin system.
