interactions of Mo(a 7S3) and Mo*(a 5S2) with methane, CH4, and ethane, C2H6, were studied under single collision conditions using the crossed molecular beams technique. Ground state Mo(a 7S3) atoms were found to be unreactive at all collision energies studied up to 〈Ecoll〉=35.4 kcal/mol. Nonreactive scattering of Mo(a 7S3) with methane and ethane was studied and compared to collisions with Ne and Ar
使用交叉分子束技术在单一碰撞条件下研究了 Mo(a 7S3) 和 Mo*(a 5S2) 与甲烷 CH4 和乙烷 C2H6 的相互作用。发现基态 Mo(a 7S3) 原子在研究高达 = 35.4 kcal/mol 的所有碰撞能量下都不反应。研究了 Mo(a 7S3) 与甲烷和乙烷的非反应性散射,并与与 Ne 和 Ar 的碰撞进行了比较。前峰值质心角分布 T(Θ) 是模拟与惰性气体的弹性碰撞以及与烷烃的非弹性碰撞所必需的。在与 CH4 的碰撞能量为 14.4 kcal/mol 和与 C2H6 的碰撞能量为 21.0 kcal/mol 时,发现非弹性碰撞分别将 10% 和 19% 的初始动能转化为烷烃内能。对于脱氢产物 Mo*(a 5S2)+CH4 的碰撞,在研究的所有碰撞能量下观察到 MoCH2,低至 2.1 kcal/mol。观察到反应Mo*(a 5S2)+C2H6→MoC2H4+H2 低至=4
