Cd3od nmr peak

WebSep 24, 2024 · If your NMR sample contains some benzene (C 6 H 6) and some acetone (CH 3 COCH 3 ), and there is a peak at 7.15 that integrates to 1 proton and a peak at 2.10 ppm integrating to 6 protons, it might mean there are 6 protons in acetone and 1 in benzene, but you can tell that isn't true by looking at the structure. WebIn carbon-13 NMR spectroscopy, the sole carbon in deuterated chloroform shows a triplet at a chemical shift of 77.16 ppm with the three peaks being about equal size, resulting from …
