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- j# o- t. S% ^ o/ f- p/ ^
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.
# o w* r2 V$ R. p1 {8 R, B
" O6 a6 L) q" m6 N7 ?; B$ P$ O7 _' 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! . e4 Z" M3 D$ D. x5 ]
