When the spectral data is sparse, the list of potential candidate structures can seem endless. The task then becomes sifting through the spectral data as a means to filter the candidates. The purpose of this puzzle is to perform such a task.
The following unknown compound with a mass of 380.1 +/- 0.5 Da comprises of the atoms C, H and O. There are 13 to17 carbon atoms expected, a minimum of 18 hydrogen atoms and a minimum of 1 oxygen atom. An expansion of the aromatic region of a 1H NMR spectrum is also provided. Given the following criteria, can the list of molecular formulae be dwindled down?
