Two-dimensional 2D Fourier transform nuclear magnetic resonance spectroscopy has been applied for the first time to a B11-H1 spin system. A heteronuclear experiment is performed on the closo-carborane, 2,4-C2B5H7, to give a 2D correlated spectrum in which chemical shift data of B11 and H1 are simultaneously displayed on a three-dimensional map. It is shown that the technique has the potential to resolve broad, overlapped B11 signals via the chemical shift of the protons to which they are scalar-coupled. Author
