    How many signals should be observed in the ""^1H "NMR .

    The methyl hydrogens, and the para hydrogen are unequivocally identified by their integration ratio. We don't know which of the remaining signals belongs to ortho or meta, but this really does not matter. By contrast, the ""^13C{""^1H} NMR spectrum should exhibit 6 peaks in the NMR spectrum, corresponding to the 6 distinct carbon environments...

    NMR Spectra of 3-nitro methyl benzoate : OrganicChemistry

    NMR Spectra of 3-nitro methyl benzoate. So the H NMR spectrum is given for the molecule pictured below, and I was wondering if someone could explain to me why it only shows four peaks where I think there should be five? To me it looks like there are five types of hydrogen in this molecule but please let me know if I'm wrong about this.

    14.13: Splitting Diagrams Explain the Multiplicity of a .

    The 1 H-NMR spectra that we have seen so far (of methyl acetate and para-xylene) are somewhat unusual in the sense that in both of these molecules, each set of protons generates a single NMR signal. In fact, the 1 H-NMR spectra of most organic molecules contain proton signals that are 'split' into two or more sub-peaks. Rather than being a complication, however, this splitting behavior actually provides …

    Determining Ethyl Benzoate from NMR and MS

    The peak at 150 indicates the molecular weight of the sample, while peaks at 65, 77, 105, and 135 all indicate fragments. For instance, the fragment which peaked at 65 is representative of the aromatic ring. Due to correlating results of both the NMR and the MS it was able to be determined that the structure of C9H10O2 was indeed ethyl benzoate.
