Abstract
Multiphoton ionization (MPI) in intense visible or UV laser fields has many interesting aspects as a source of information about energetic polyatomic molecules (ions)1–11. An important feature is that by adjusting laser intensity and wavelength one has a rather complete control over the extent of the fragmentation accompanying MPI. Several factors make MPI of interest for mass spectroscopy. Among these are the effective ionization by lasers and the possibility of two-dimensionsional (mass and laser wavelength) mass spectrometry. Also high selectivity with respect to conventional mass spectrometry is obtained and useful e.g. to distinguish between isomers of organic compounds12. MPI has also interesting applications in condensed phases, e.g. ionization studies in liquids13,14 or laser desorption of molecules from surfaces15.
