WebMar 15, 2016 · Although the chemical shift scales are still zeroed at the TMS peak, most spectra are now calibrated against the residual solvent peak. Typically, deuterated solvents such as $\ce{CDCl3}$ and $\ce{DMSO}$-$\ce{d6}$ are used and these contain a very small amount of undeuterated, or partially deuterated, solvent which produces a peak in … WebMar 15, 2016 · Although the chemical shift scales are still zeroed at the TMS peak, most spectra are now calibrated against the residual solvent peak.

WebApr 10, 2024 · The mass spectrum of the bis-Schiff base ligand (H 2 L) showed that the molecular ion peak is in good agreement with its suggested empirical formula. The ion peak owing to m/z 348.53 corresponded to the molecular weight of the Schiff base ligand (348 g/mol) with the empirical formula C 20 H 16 N 2 O 4.The mass spectrum of the Schiff … WebJul 15, 2024 · 1H-NMR of DMSO-d6. Deuterated dimethysulfoxide (DMSO-d6) is usually sold at least 99% deuterium (D) rich. D is NMR-active and bear a magnetic moment I = 1. Applying the rule "2NI+1" for the multiplicity, one gets 2·3·1+1 = 7 (the CD3 groups are equivalent). That's why DMSO-d6 gives a septet centered at 39.52 ppm. WebView the Full Spectrum for FREE!
