Ethanol spectra

WebThe second, smaller spectrum at top is a 13C spectrum. The 13C spectrum uses a slightly different form of analysis to probe the electronic environments of the carbons in a sample. Because there are two carbons in ethanol, two main peaks are seen. The rest of the peaks are the solvent (CDCl3) or impurities. WebThe spectra also include well resolved, higher absorption overtones. The instrument achiev … In this work we report on the absorption spectra of ethanol and water in the region …
