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:
' ?& d, Q8 m% a! ^ 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. . z, w* J0 f- Q: C+ @; Y# b4 o
: w! w! p1 M& ^" B+ n
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! 2 c2 u2 f7 R4 A% [% j/ ]
