利用高分辨弱电场加速型光解碎片平动能谱仪，对CF3I在238 nm的光解动力学进行了研究.结果表明，来自3Q0平行跃迁的I*通道[CF3I（X）→CF3I（3Q0）→CF3（ν1，ν2）+I*]，信号最强，并可以分辨出碎片CF3（ν1，ν2）的振动峰.通过对峰间距的分析，可以基本分辨出同时具有CF3碎片的振动波带CF3（ν1，ν2=0）与CF3（ν1，ν2=1）.其中ν1 =701 cm-1为对称...

本文用TEA CO_2激光9.6R(14)支作激发光源, 富里叶变换红外光谱仪作分析手段, NO, O_2作CF_3自由基的捕捉剂, 研究了CF_3I红外多光子解离的动力学。
实验发现, O_2和NO均可用来捕捉CF_3I的红外光解产物CF_3自由基。从对CF_3I的红外多光子解离率与外加气体压力的变化关系的研究, 以及CF_3I红外多光子吸收的测量, 揭示出该分子在受红外激光激发时, 具有小分...
