    1H NMR - Integration - WFU

    Integration. The area under the NMR resonance is proportional to the number of hydrogens which that resonance represents. In this way, by measuring or integrating the different NMR resonances, information regarding the relative numbers of chemically distinct hydrogens can be found. Experimentally, the integrals will appear as a line over.

    NMR Scale: NMR spectra are scaled in units of parts per million. This measurement is used because there are such small differences in the applied magnetic fields required to excite each nuclei to a higher energy state. 1H NMR scale ranges from 0 ppm to 10 ppm while 13C scale ranges from 0 …

    1H NMR - Num of Diff Hydrogens - users.wfu.edu

    Ethyl acetate contains 8 hydrogens and some of them are different from each other. For example, those labeled A are attached to a carbon bonded to a carbonyl group and are different from the hydrogens labeled B which are bonded to a carbon attached to an oxygen atom.

    Ethyl acetate - Wikipedia

    Ethyl acetate is the organic compound with the formula CH 3–COO–CH 2–CH 3, simplified to C 4H 8O 2. This colorless liquid has a characteristic sweet smell and is used in glues, nail polish removers, decaffeinating tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. The combined annual production in 1985 of Japan, North America, …
