How to Interpret EI-MS Spectra
Abstract:
EI-MS is a frequently adopted technique which can provide rich information in compound structures. The following properties can be retrieved directly from the mass spectrum of an unknown compound, including the molecular or fragment ion peak, odd or even charge and mass, elemental numbers (C, N, Si, Cl, Br, etc.). It is a basic skill to be able to acquire the aforementioned information from the mass spectrum.
