| 英文摘要 | Energy transfer reactions of metastable He(2 3S) with methane and chloromethane molecules were investigated by measuring the emission spectra of the electronically excited fragments under beam conditions. The formation rate constants of the fragments CH(A 2DELTA), CH(B 2SIGMA-), CH (C 2SIGMA+), H* and CCl(A 2DELTA) for the reactions He(2 3S) + CHNCl4-n (n=1-4) have been determined. The nascent rovibrational distributions of CH(A 2DELTA, upsilon'=0-2) and CH(B 2SIGMA-, upsilon'=0) have been obtained. The experimental results show that the rotational distribution of CH(A 2DELTA, upsilon'=0) from the reaction of He (2 3S) with methane is different from that of He(2 3S) with chloromethanes. In the former case, the rotational distribution can be expressed by a single Boltzmann temperature, while in the latter it is not a complete equilibrium distribution and may be expressed by a double Boltzmann distribution. A discussion of the reaction mechanism based on statistical theory is presented. |
