Br(CF 2)4 COI分子通过C stretchingO(1794 cm -1)拉伸和骨架(961 cm -1)振动激发而进行红外多光子解离
摘要:
研究了TEA CO 2激光的二次谐波(通过CO拉伸)和一次谐波(通过骨架振动)引起的红外多光子激发(IR-MPE)引起的Br(CF 2)4 COI分子的解离。发现在两种情况下,IR-MPE通过两个不同的通道发生解离,最终形成C 2 F 4和Br(CF 2)4 I分子。同时,发现这些最终产物的相对比例取决于分子激发的通道。

Dissociation of Br(CF2)4COI molecules resulting from infrared multiple-photon excitation (IR-MPE) by the second (via CO stretch) and the first (via skeleton vibrations) harmonics of TEA CO2 laser was studied. It was found that in the two cases of IR-MPE, dissociation occurs via two distinct channels with the formation of C2F4 and Br(CF2)4I molecules as final products. At the same time, the relative
