Quasi-classical Trajectory Calculation of the Chemical Reactions Ba+C₆H₅Br, m-C₆H₄CH₃Br

摘要

In this paper, the reactive dynamics properties of the reactions Ba + C6H5Br and Ba + m-C6H4CH3Br were studied by means of the quasi-classical trajectory method based on the London-Eyring-Polanyi-Sato potential energy surfaces. The vibrational distributions, reaction cross sections, rotational alignments of the products BaBr all were obtained. The peak values of the vibrational distributions are located at ν = 0 for the reactions Ba + C6H5Br and Ba + m-C6H4CH3Br when the collision energies are 1.09 and 1.10 eV, respectively. The reaction cross sections increase with the increasing collision energy, which changes from 0.6 to 1.5 eV. The product rotational alignments deviate from −0.5 and firstly increase and then decrease while the collision energy is increasing, just like that of Heavy+Light-Light system.
