Spectroscopy Unknown Practice 3 Spectroscopy Unknown. The spectra and data provided were obtained from a pure organic molecule. For 1H NMR Spectra, the integral is given in number of hydrogens (\#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given showing a "zoom-in" on an important part of the spectrum. Mass Spectrum (not shown): 189m/2 (100\%) IR Spectrum (not shown): 3042,2982,2932,2246(m),1601,1498cm1 (all listed are strong (s) unless otherwise indicated) Spectroscopy Unknown Practice 4 Spectroscopy Unknown.
