• 中文摘要： 我們回顧了雷射光分解法和再結合反應螢光偵測法混合技術的發展過程。新發展的方法能確用來量度活性原子的再結合反應速率常數及其擴散係數。我們量得氯原子在Ar，(方程式無法摘錄) 和 (方程式無法摘錄) 裹的再結合反應速率常數，並和傳統方法得到的速率常數互相比較。我們也量得氯原子及溴原子在惰性氣體及穩定分子內的擴散係數並和其相鄰的惰性氣體的擴散行為互相比較。我們也由分子束碰撞實驗得到的鹵素原子和惰性氣體間的作用位能曲線，計算出鹵素原子在惰性氣體中的擴散係數，再和我們所量得的擴散係數互相比較。
• 英文摘要： The development of the laser-photolysis-recombination-luminescencedetection method is reviewed.By this method one can measure the recombination rate constants and the diffusion coefficients of halogenatoms in rare gases and inert molecular media. The recombination rate constants of chlorine atoms in Ar, (方程式無法摘錄) ,and (方程式無法摘錄) gases were measured and compared with the values obtained by conventional techniques ofmeasurement. The diffusion coefficients of bromine and chlorine atoms in rare gases were obtained and arecompared with the corresponding neighboring rare gas-rare gas diffusion coefficients. The diffusion coef-ficients of halogen-rare gas systems were also calculated from the interaction potentials obtained by themolecular beam scattering experiments. The agreement between the present results and the calculatedvalues is very good. The diffusion coefficients of the halogen atoms in inert molecules are also reported.
