Spectroscopy Unknown. The spectra and data provided were obtained from a pure organic molecule. For 1 H 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): [M] = 169 (100%) m/z IR Spectrum (not shown): 2985,...
