摘要
The cross polarization condition for hetero-coupled NMR spectroscopic investigations for a sample spinning a rate ωR is improved by causing at least one of the RF excitation channels to emit pulses in synchronous relationship to the sample spinner during the cross polarization contact whereby dependence of the NMR signal on mechanical spin rate ωR is reduced.
