| 摘 要： | 本文提出一种改进的多量子相干选择检测(滤波)方法。滤波Z脉冲分别在准备期和混合期末。它能有效地防止单量子相干的"漏进"并避免使用数字相移器。在一般谱仪上容易实现,用密度算符理论对AMX体系进行理论计算,实验结果与理论预期相符。

| Abstract: | It is provided that a modified method for selective detection of multiple-quantum coherences in which a pair of Z pulse is used separately at the end of preparation and mixing period in 2D MQ spectrocopy can efficiently decrease the "leakage" from SQC signals and needn't use the digital phaser. Theoretical calculation for AMX spin system with density operators is given and coincides with the results of experiments. |
