The Structure of Small Molecules and Ions as Determined by Photoionization Mass Spectrometry
Photoionization mass spectrometry (PIMS) is an extremely versatile spectroscopic technique for the investigation of molecular ions and their parents. Whenever relative photoion yields and accurate adiabatic and appearance potentials are needed, PIMS is the method of choice. Judiciously used, the information obtained by this technique becomes a powerful basis for inferring the electronic and geometric structure of small molecules and ions. We shall corroborate this assertion by presenting a couple of recent studies from our laboratory.
