We obtained similar results from the non H-exposed Cl sample. By plotting the Arrhenius relations we were able to obtain the activation energies for each set. From the set with H-exposure we obtained 1.23eV for inter-dimer hoppings and 0.70eV for intra-dimer hoppings respectively, while for the set without H-exposure we obtained 1.14eV and 0.62eV for the inter-dimer and intra-dimer hoppings respectively.

由Arrhenius 关系线，我们推算出氢-氯原子交换运动的动力能障，即对於曝氢而言inter-dimer跳跃的动力能能障为1.23 eV、至於intra-dimer跳耀的动力能则为0.70 eV，相对的，在对於没有曝氢的inter-dimer跳耀的动力能为1.14 eV，intra-dimer跳耀的动力能则是0.62eV。
