The Supporting Information section of the article provides detailed NMR chemical shift data for trace impurities found in common laboratory solvents, organics, and gases when deuterated. The corrections and comments section addresses several errors in the original paper, including misreported 1H NMR chemical shifts for acetic acid, acetonitrile, and tert-butyl alcohol in C6D6, as well as incorrect assignments for BHT's C(3,5) and C(4) in various solvents. The resonances for 1,2-dimethoxyethane, silicone grease, and 2-propanol have also been corrected. Additional data, such as the OH resonance for ethanol in C6D6 and the CH3 resonance for silicone grease in (CD3)2SO, are provided. The section includes tables of 13C{1H} NMR data by chemical shift for various deuterated solvents, including THF-d8, CD3Cl3, CDCl3, toluene-d8, C6D6, C6D5Cl, (CD3)2CO, (CD3)2SO, CD3CN, TFE-d4, CD3OD, and D2O.The Supporting Information section of the article provides detailed NMR chemical shift data for trace impurities found in common laboratory solvents, organics, and gases when deuterated.
