WebMay 29, 2009 · Why is CDCl3 a Triplet? Posted by naturalproductman on May 29, 2009. Ever wonder why when you’re taking a 13C NMR in deuterated chloroform and look at the solvent peak – there are three evenly spaced peaks with equal intensities? The answer can be found in your good old sophmore organic chemistry textbook (*I recommend the Marc …

WebOct 1, 2024 · DMSO is a much better solvent that chloroform (much more polar and more polarizable than chloroform, and a potent hydrogen bond acceptor to boot)--there aren't many molecular substances that aren't soluble in DMSO, at least enough to get a decent NMR (it's ok for some polymers and some salts as well).

WebWe have seen that 13 C NMR is usually decoupled and therefore there is no splitting of signals which limits the information we can get as to how many hydrogens are connected to a carbon atom. And even combining 1 H and 13 C NMR spectra may not give definite evidence for choosing only one structure.
