AN INVESTIGATION ON THE EXPERIMENT SETUP FOR THE MOLECULAR SPECTRUM AND MOLECULAR PHOTODISSOCIATION DYNAMICS

In this paper, we presented the key structure and functions of our newly made experiment setup for the study of the molecular spectrum and the molecular photodissociation dynamics. Its characteristic is that on it we can carry the study of laser photolysis and laser induced plasma and laser induced fluorescence and resonance enhanced multiphoton ionization and time of flight mass spectrum. The research that can be carried on this experimental apparatus were also reviewed in detail,just as: the investigation on the resonance enhanced multiphoton ionization of molecule and radical, the study of the laser induced fluorescence and resonance enhanced multiphoton ionization of mental radical, the study of the photodissociation dynamics of polyatomic molecule. The preliminary experiment result of time of flight mass spectrum of CS_2 produced by laser resonance enhanced multiphoton ionization was obtained.
