HMQC and HSQC experiments are very commonly applied to 1H - 13C and 1H - 15N. These techniques can also be applied to other isotopes. The figure below shows the 1H - 11B HMQC spectrum or ortho-carborane. The top and side traces are separately acquired 1H [11B] and 11B [1H] spectra, respectively. These data, combined with the 11B COSY data, allow the complete assignment of the 1H [11B] spectrum.
Thank you to Dominique Duguay for providing the sample of ortho-carborane.
