Highlights

?The performance of multiCP has been improved by composite 90° pulses on the X-channel.

?The composite pulses reduce the sensitivity to flip-angle errors and resonance offset.

?A wider amplitude ramp can be used, reducing sensitivity to Hartmann-Hahn mismatch.

?Partial dipolar dephasing improves match of multiCP with DP spectrum ifT1ρis short.

?Quantitative13C spectra of hard–soft polymer systems have been obtained.

？通过X频道上的复合90°脉冲改进了Multicp的性能。？复合脉冲会降低触发的灵敏度LE错误和谐振偏移。

？可以使用更广泛的振幅斜坡，从而减少对Hartmann-Hahn Mismatch的敏感性。

？部分偶极脱位改善了多种与DP频谱的匹配，如果 t 1ρ很短。

？定量 13 c谱的硬质聚合物系统已获得。
