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.
