In magic angle spinning solid state NMR experiments the potential of heteronuclear (1)H decoupling employing a continuous train of adiabatic inversion pulses has been assessed via numerical simulations and experimental measurements. It is shown that, with a (1)H RF field strength of approximately 100 kHz that is typically available in MAS NMR probes, it is possible to achieve efficient adiabatic (1)H decoupling at low magic angle spinning frequencies. It is pointed out that in the presence of H (1) inhomogeneities it will be advantageous to employ adiabatic decoupling in MAS solid state NMR experiments.
