5.14.3 1 H NMR Spectrum of a Mixture of Common Nondeuterated
Solvents
The following 1 H NMR spectrum (500 MHz, δ in ppm relative to TMS) of CDCl 3
containing 18 common solvents (0.05–0.4 vol%) is shown as a guide for the identification of possible impurities. Where the signals of several solvents overlap, insets
show signals for the individual compounds from separate spectra. Peaks in these
insets are labeled with the corresponding chemical shifts from their main spectrum
but their values may differ by up to 0.03 ppm. Signals that are particularly prone to
vary in their position are marked with *. THF: tetrahydrofuran; EGDME: ethylene
glycol dimethyl ether.
