朋友们,我在看一篇定量分析文章时,他的仪器参数(布鲁克NMR)为: # }& b& z& C% ?6 U
30? hard excitation pulse, spectral width 16 ppm, 6μs preacquisition delay, 32K points in the time domain, 256 scans and a relaxation delay of 10 s to ensure complete relaxation for all signals. ! T* D) {0 e$ i' w1 l7 T( ~
) G9 c2 Y; u( f% w+ D- Z6 L 我想请问下Preacquisition delay 和 Relaxation delay 的区别?我用的是瓦里安的NMR,relaxation delay 好像指的是d1参数,那么Preacquisition delay在瓦里安仪器上又指的那个参数了?我是菜鸟,请大家多帮帮忙哈,先谢谢! & \9 Y4 n5 h" k2 V' R8 @. z
