Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

Question

In order to determine high and low electron density, is it necessary to include minor resonance structures? The textbook answer says 'significant resonance contributors suggest the areas of highest and lowest electron density.' Does this mean minor structures are also significant?
