We are asked which of the following determines the peak height in a mass spectrum.


Electrons are beamed at molecules, generating high energy intermediates called radical cations 

● Only fragment cations are deflected by the magnetic field, the smaller ones more than the bigger ones. 

             □ Detects the mass-to-charge ratio M/Z, which means that it detects the MW of cationic fragments
