The rate constant in chemical reactions provided important information. The reaction rate constant predicts how fast the reaction would take place and could be further applied to the dissociation of the substance of interest. In this reason, measurement of rate constant is highly critical. In our lab, experiments relevant to ternary cluster rate constant have been performed. However, the data of experiments and Phase Space Theory (PST) did not match well. To overcome such problem, we will employ Rice-Ramsperger-Kassel-Marcus (RRKM) theory which is easy to access to interpret the experimental results thoroughly. Experiment of 1-Bromo-3-chlorobenzene Cation (3-BrClBz) will be also carried out to verify if molecules also follow the same tendency. Benzene is one of most useful solvents in chemical reactions. In addition, the halogen group is a well-known functional group. Using Time of Flight (TOF) mass spectroscopy we will investigate the internal energy dependence of branching ratio with Modified RRKM theory. The Branching ratio of 3-BrClBz will be obtained at different internal energies (4.37, 4.55, 4.78 eV). The results of the experiments and Modified RRKM calculations are expected to match well.
