  • Title: Multiplicity-edited broadband HMBC NMR spectra.
    Author: Nyberg NT, Sørensen OW.
    Journal: Magn Reson Chem; 2006 Apr; 44(4):451-4. PubMed ID: 16425209.
    Abstract:
    A new, edited HMBC experiment is introduced that leads to two subspectra according to the number of protons attached to 13C nuclei being even or odd, i.e. one subspectrum with C + CH2 and another with CH + CH3. This experiment can be useful for resolving spectral overlap among the typically large number of peaks in HMBC spectra. It is implemented in a broadband version similar to broadband HMBC and demonstrated on prednisolone [(11beta)-11,17,21-trihydroxypregna-1,4-diene-3,20-dione].
