Popis: The 1H and 13C NMR chemical shifts of 48 industrially preferred solvents in six commonly used deuterated NMR solvents (CDCl3, acetone-d6, DMSO-d6, acetonitrile-d3, methanol-d4, and D2O) are reported. This work supplements the compilation of NMR data published by Gottlieb, Kotlyar, and Nudelman (J. Org. Chem. 1997, 62, 7512) by providing spectral parameters for solvents that were not commonly utilized at the time of their original report. Data are specifically included for solvents, such as 2-Me-THF, n-heptane, and iso-propyl acetate, which are being used more frequently as the chemical industry aims to adopt greener, safer, and more sustainable solvents. These spectral tables simplify the identification of these solvents as impurities in NMR spectra following their use in synthesis and workup protocols.
