我们展示了如何直接光谱优化可以用来提供显着提高分辨率的质子NMR光谱在固态。我们描述了新的连续相位调制方案的设计质子-质子homopolybipolar去耦，利用实验优化程序，通过观察碳-13线形。所得到的eDUMBO homestone去耦序列的性能证明了各种高分辨率质子NMR实验在500和700 MHz，并在不同的魔角旋转速度。(C)2004 Elsevier B. V.保留所有权利。
We show how direct spectral optimisation can be used to provide significantly improved resolution for proton NMR spectroscopy in the solid state. We describe the design of new continuous phase modulated schemes for proton-proton homonuclear dipolar decoupling, exploiting an experimental optimisation procedure through observation of carbon-13 lineshapes. The performance of the resulting eDUMBO homonuclear decoupling sequences is demonstrated with a variety of high resolution proton NMR experiments at 500 and 700 MHz, and at different magic angle spinning speeds.
