NMR Chemical Shifts of Common Laboratory Solvents as Trace Impurities Hugo E. Gottlieb,* Vadim Kotlyar, and Abraham Nudelman* Department of Chemistry, Bar-Ilan University, Ramat-Gan 52900, Israel Received June 27, 1997 In the course of the routine use of NMR as an aid for organic chemistry...
Also, any potential hydrogen- shifts of what are, in our experience, the most popular bond acceptor will tend to shift the water signal down- “extra peaks” in a variety of commonly used NMR field; this is particularly true for nonpolar solvents. In solvents, in the hope that this will...
The solvent chemical shifts3 were obtained from the spectra containing the solutes, and the ranges of chemical shifts (2) I.e., the signal of the proton for the isotopomer with one less deuterium than the perdeuterated material, e.g., CHCl3 in CDCl3 or C6D5H in C6D6. Except for ...
NMR Chemical Shifts of Trace Impurities: Common Laboratory Solvents, Organics, and Gases in Deuterated Solvents Relevant to the Organometallic Chemist Tables of ^1H and ^(13)C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products o...
The 1H- and 13C-NMR chemical shift values of 1-n-butyl-3-methyl (BM)- and 1-ethyl-3-methyl (EM)-substituted imidazolium (IM) -chlorides (Cl) and -acetates (Ac) are determined before and after diluting with deuterated solvents (DMSO-d6, D2O, CD3OD, and CDCl3). The dilution ...

http://www.chem.wisc.edu/areas/reich/handouts/nmr-h/hdata.htm There is also a good paper on the chemical shifts of various common impurities in many deuterated solvents. If you don't have that paper, I can find the reference. Logged ...
FT-Raman spectroscopy can be used to probe protein-protein interaction noninvasively in different solvents. Ngarize et al. (2004) investigated gelation of small and similarly charged whey and egg white proteins together under different thermal conditions in deuterated water (D2O). Synergistic ...
