"Parent" ion.s are formed when a single electron is removed from a molecule. 

 Only the positively charged ions with masses greater than 66 are recorded in 

 TABLES 4 through 8. 



A saturated hydrocarbon may yield a variety of ions. Any compound can 

 form a greater number of small than of large fragments, and large molecules 

 can produce more fragments than can small molecules. It is for these reasons 

 that the values (peak heights) in tables 4, 5, and 7 generally decrease from the
