英文摘要	the photodissociation dynamics of propyl iodides n-c3h7i and i-c3h7i near 280 and 304 nm has been investigated with our mini-tof photofragment translational spectrometer. when a single laser is applied for both the photodissociation of parent molecules and the rempi of i atom photofragments, the tof spectra of photofragments i('p-1/2) and i (p-2(3/2)) are obtained at four different wavelengths for these two iodides. for n-c3h7i, some small vibrational peaks are partially resolved (with separation of similar to 522 cm(-1), corresponding to the rch2 deformation frequency of the fragment n-c3h7) at 281.73, 279.71, and 304.67 nm. these results show that the rch2 deformation is mostly excited. for i-c3h7i, we obtain some partially resolved vibrational peaks (with separation of similar to 352 cm(-1), corresponding to the hc(ch3)(2) out-of-plane bending frequency of the fragment i-c3h7) at 281.73 nm only. for n-c3h7i, the partitioning values of the available energy (e) over bar (int)/e-avl are 0.48 at 281.73 nm and 0.49 at 304.02 nm for the i channel, and 0.52 at both 279.71 and 304.67 nm for the i channel. these energy partitioning values are comparable with the previous results at different wavelengths in the literature. for i-c3h7i, the (e) over bar (int)/e-avl values are 0.61 at 281.73 nm, 0.65 at 304.02 nm for the i* channel, and 0.62 at 279.71 nm, 0.49 at 304.67 nm for the i channel. the potential-energy-surface crossing and the beta values have also been discussed.
