Hadamard NMR spectroscopy in solids

摘要: The duration of 2D and 3D NMR experiments in solids can be reduced by several orders magnitude using frequency domain Hadamard encoding with long selective pulses. We demonstrate encoded 13C enriched samples. To avoid multiple quantum interferences, the pulses are applied sequentially rather than simultaneously this study. Among other possible applications, dipolar assisted rotational resonance measurement NOESY type build-up rates proton driven spin diffusion demonstrated.
