Abstract:
This tutorial review presents the technique of infrared multiple-photon dissociation (IRMPD) spectroscopy of mass-selected trapped ions. This requires coupling of a tunable infrared laser with mass spectrometry instrumentation. IRMPD spectroscopy has recently blossomed due to the emergence of widely tunable free electron lasers, as well as on-going developments of benchtop lasers. The merits of different trapping approaches in mass spectrometry are discussed in the light of photodissociation experiments. This tutorial discusses current capabilities, as well as limitations of the technique.
