Different types of spectroscopy can be used to identify the structure of unknown compounds. Some common spectroscopy methods are NMR- spectroscopy, IR-spectroscopy, UV-visible spectroscopy, Mass spectroscopy, etc.
The IR-spectroscopy provides information about the presence of functional groups whereas NMR spectroscopy gives data about types of H present in the molecule.
The molecular ion peak is used to determine the molecular weight of the given compound. It is the peak with the highest value of m/z in the mass spectrum.
In the given spectrum the molecular ion peaks are:
Molecular ion peak = 78
Molecular ion peak = 136
molecular ion peak = 59
