## Abstract The ability of Paul and Penning traps to contain ions for time periods ranging from milliseconds to minutes allows the trapped ions to be subjected to laser irradiation for extended lengths of time. In this way, relatively lowβpowered tunable infrared lasers can be used to induce ion fr
InCnred mulIiple-pholon decomposiIion (IRMPD) or Fe(CO), induced by an IR p-H1 Raman laser has been srudied.
