Document Summary

Peak in a mass spectrum due to the ion wl greatest relative abundance not always molecular ions molecular ion molecule that has been ionized by e loss but not fragmented fragment ion ion formed by fragmentation. Process that breaks molecular ion into smaller ions , radicals or neutral molecules isotope group of atoms with. Protons but diff neutrons ( ex : rc. 14c ) mass spectrum plot of relative ion abundance ( 4- axis ) Miz mlz ratio of ion "s mass ( m ) in amu to its formal charge. +1 ) radical cation ion that has both a. Fc ( cation and an unpaired e radical of s s of. 1) a sample is introduced in the ionization chamber where it"s bombarded. If an e collides wl a molecule an e is. Plate in the chamber ( and attracted to the negatively charged plate ) .
