WebI am guessing each peak is 2 times that of a normal CH2 peak since there will be 4 protons in each chemical environment. Any help is appreciated. That is not a spectrum of cyclopentanone - its a computer guess of what it would look like. The H-NMR would have two roofed triplets in that region, the one closer to the ketone will have the higher ... http://homework.sdmesa.edu/dgergens/chem231L/NMR/NMR_sample_report.pdf
