Spectroscopy Unknown
Spectroscopy Unknown. The spectra and data provided were obtained from a pure organic molecule. For iH NMR Spectra, the integral is given in number of hydrogens (th) 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.
