Tables of 1H and 13C NMR chemical shifts have been compiled for common organic compounds often used as reagents or found as products or contaminants in deuterated organic solvents.

These tables can support you in identifying and separating NMR signals of impurities that might originate from residual solvents or from your reaction apparatus. Here we present the NMR …

2010年4月16日 · Tables of 1H and 13C NMR resonances for common organic contaminants are reported in 12 different deuterated organic solvents frequently used to study organometallic …

2015年12月23日 · ABSTRACT: The 1H and 13C NMR chemical shifts of 48 industrially preferred solvents in six commonly used deuterated NMR solvents (CDCl3, acetone-d6, DMSO-d6, …

Use this reference table to find the coupling values and chemical shifts of our NMR (deuterated) solvents. Melting and boiling points, molecular weight, density, and CAS number are also listed.

We therefore decided to collect 1H and 13C chemical shifts of what are, in our experience, the most popular “extra peaks” in a variety of commonly used NMR solvents, in the hope that this …

* HOD Peaks - NMR spectra of “neat” deuterated solvent always exhibit a peak due to H 20 in addition to the residual solvent peak. When the exchange rate between H 0 and HDO is slow …

Most NMR spectra are recorded for compounds dissolved in a solvent. Therefore, signals will be observed for the solvent and this must be accounted for in solving spectral problems. To avoid …
