NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have...

aIt looks like solvent peaks shown on NMR. You can use vacuum pump to remove solvent, the temperature is 60 degrees, It may takes 5-6 hours. 它看似在核磁共振显示的溶解的峰顶。 您能使用真空泵去除溶剂,温度是60度,它可以作为5-6个小时。 [translate] ...
Typically solvent peaks are the dominant feature in the NMR spectrum and often mask or seriously overlap smaller resonance from which important information of the molecule under study may be obtained. Although applied to NMR spectra, the method is general and may be applied to large peak ...
Occasionally, in order to distinguish between peaks whose assignment was ambiguous, a further 1-2 ?L of a specific substrate were added and the spectra run again. 7514 J. Org. Chem., Vol. 62, No. 21, 1997 Table 2. CDCl3 solvent signals CO CH3 acetone CO CH3 acetonitrile CN CH3 ...
