چکیده
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes
were studied. The influence of the substituent group on the fragmentation
modes of the molecular ions is discussed. The effect of pressure in the
formation of negative ions was also studied. As expected, the ratio of fragment
ions to negative molecular ions decreased with increasing pressure in ion
source.
