英文摘要 | When a heteronuclear multiple quantum coherence (HMQC) NMR experiment is performed in one-dimensional mode, due to the wide range in chemical shift of the indirectly detected spin and the limited strength of the radio-frequency field, the off-resonance effect on the intensity of the observed signal can be serious. In this paper, the effect is studied using the spin-density-matrix formalism and simulations of the experimental results are presented. The bilinear rotation-decoupling sequence (BIRD), which is usually used in HMQC experiments, is also discussed. It is shown that the BIRD sequence has a negative effect by virtue of narrowing the excitation band. |
