| 英文摘要 | the photodissociation of ethyl iodide at 279.71, 281.73, 304.02 and 304.67 nm has been studied on our new mini-photofragment translational spectrometer with a total flight path of only 5 cm. some vibrational peaks are firstly resolved in the tof spectra of i*(p-2(1/2)) and i(p-2(3/2)) channels. these vibrational peaks are assigned to the excitation states (v(2) = 0, 1, 2,---) of the umbrella mode (v(2), 540 cm(-1)) of the photofragment ca, and the distribution of the vibrational states is obtained. the dissociation energy has been determined to be d-0(c-i)=2.314 +/- 0.03 ev. the energy partitioning of the available energy (e-avl=e-t+e-int = e-t+e-v,e-r) calculated from our experimental data e-int /e-avl = 22.1% at 281.73 nm, 22.4% at 304.02 nm for the i* channel, and e-int /e-avl = 25.2% at 279.71 nm, 25.9% at 304.67 nm for the i channel, seem to be more reliable. |
