Abstract
New schemes are introduced that allow one to improve the resolution in the indirect dimension of single-scan 'ultrafast' two-dimensional NMR spectra. The methods combine undersampling with band-selective pulses to recover signals that lie outside the detection bandwidth. The efficiency is illustrated for homonuclear total correlation spectroscopy (TOCSY) of quinidine.
摘要
引入了新的方案，这些方案能够提高单扫描“超快”二维核磁共振谱间接维度的分辨率。这些方法将欠采样与带选择性脉冲相结合，以恢复位于检测带宽之外的信号。以奎尼丁的同核全相关谱（TOCSY）为例说明了该方法的有效性。
