Internal Energy and the Further Fate of Ions

When an analyte is transferred into the ion source by means of any sample introduction system it is in thermal equilibrium with this inlet device. As a result, the energy of the incoming molecules is represented by their thermal energy. Then, ionization changes the situation dramatically as comparatively large amounts of energy need to be handled by the freshly formed ion. [Pg.21]


This indicates that excited vibrational states are almost fully unoccupied at room tenperature and only the energetically much lower-lying internal rotations are effective under these conditions. Upon electron ionization, the situation changes quite dramatically as can be concluded fiom the Franck-Condon principle and therefore, energy storage in highly excited vibrational noodes becomes of key importance for the further fate of ions in a mass spectrometer. In case of an indene... [Pg.31]
