Part 5: Putting It All TogetherWe don't quite have all the parts of an NMR analysis yet, but we can go a long way to solving the structure of a moleculejust by considering the number, chemical shifts, and in the case of 1H NMR, the integrals of the signals. In the nextpages, a compilation of 'H and 13C NMR spectra are shown for all but one of the organic compounds shown below. Yourjob is to match the compound with the spectra. Don't just write the structure, some justification for your choices must begiven as well.`NO2HONO2 Rel. integral = 2%3D111106.32120018016014012010080604020ppmppmHSP-03-494Cos-03-488CompoundWhy?Rel. integral = 1.5%3D112 separatepeaks111076431O 20018016014012010080604020ppmppmHSP-04-323CDS-05-1688-
