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: ( n3 L W. ~9 R- o* |: O- A; V
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. & ~! f+ l8 o- M x$ V2 ~
y; ?+ G# \1 v4 I# ]; z0 y A 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! . k3 F* D% \ \( u3 K6 w& d
