Multiphoton Ionization and Dissociation of Mn2(CO)10 in a Supersonic Molecular Beam
Abstract:
The multiphoton ionization and dissociation of Mn2(CO)10 in a supersonic moleclar beam is investigated with a XeCl excimer laser (308nm) and a tunable dye laser(430 ~ 448nm). The main fragment ions detected by a time-of-flight mass spectrometer include Mn+, Mn(CO)x+(x≦5), Mn2(CO)y+ (y≦9) and the parent molecular ionMn2(CO)10+. Additionally, metal cluster ions Mni+(i=2,3,4) and metal carbonyl cluster ions Mn3(CO)9,10+ and Mn4(CO)10+ are also detected. The Mn+ ion might be produced via a sequential photodissociation to form Mn atoms. The mechanism of the laserinduced multiphoton ionization and dissociation is discussed.
