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.
