Spectroscopy Unknown Practice 1 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 (HH) 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): 162m/z(100%) IR Spectrum (not shown): 3031, 2972, 2934, 1712, 1604, 1495 cm1 (all listed are strong (s) unless otherwise indicated) 1HNMRSpectrum(400MHz,CDCl3,25C ) 13C NMR Spectrum (with DEPT), proton-decoupled (125MHz,CDCl3,25C) Spectroscopy Unknown Practice 2 Spectroscopy Unknown.
