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.
在魔角旋转固态核磁共振实验中，通过数值模拟和实验测量评估了采用连续绝热反转脉冲序列进行异核（1）H去耦的潜力。结果表明，在魔角旋转核磁共振探头中通常可获得约100 kHz的（1）H射频场强下，在低魔角旋转频率下实现高效绝热（1）H去耦是可能的。需要指出的是，在存在H（1）不均匀性的情况下，在魔角旋转固态核磁共振实验中采用绝热去耦将是有利的。
