| 摘 要： | 用分子束和飞行时间技术测量了248 nm激光光解过程C_2H_5I→C_2H_5+I°(~2p_(1/2))和C_2H_5I→C_2H_5+I(~2p_(3/2))裂解碎片的平动能和内能分布。测得通道比I~*/I为2.37。根据实验结果, 对光解过程中电子激发态特性, 产生I(~2p_(3/2))通道的机理以及乙基自由基的振动激发作了讨论。

| Abstract: | The translational and internal energy distributions of the photofragments for the processes C_2H_5I→C_2H_5+I~*(~2p_(1/2)) and C_2H_5I→C_2H_5+I(~2p_(3/2))have been measured by using a rotatable molecular beam and time of flight method. The ratio I~*/I determined is 2.37. The characteristics of the electronic excited state, the origin of the I(~2p_(3/2)) channel and the vibrational excitations in the ethyl radicals are discussed. |
