Exploring the homopolar dehydrocoupling of ammonia borane by solid-state multinuclear NMR spectroscopy

Solid-state ¹H–¹⁴N^OT HMQC, ¹¹B MQMAS and ¹H–¹¹B HETCOR NMR experiments are used to explore the role of homopolar B–B interaction in the thermal dehydrogenation of pure and supported ammonia borane, for it's potential hydrogen storage applications.
