The I2 product vibrational state distributions are obtained by measuring the dispersed B -> X fluorescence and analyzing the resulting spectra; excitation above the B state dissocn. limit leads to significantly different reaction dynamics compared to excitation of the bound levels of the B state studied previously. Among others the recoil energies of the I2 and M fragments are much larger, and the distributions of rovibrational states in the I2 product are much wider in the present expts. The relative translational energy in the I2* and M photodissocn. products is significantly larger than predicted by recent quasi-classical trajectory calcns. The fragment recoil energy does not vary strongly with the excitation wavelength.7439-90-9; 7440-01-9 (Neon); 7440-37-1 (Argon); 7440-63-3 Role: RCT (Reactant)RACT (Reactant or reagent) (photodissocn. of van der Waals complex ofwith iodineproduct vibrational state distributions in); 7553-56-2 (Iodine) Role: RCT (Reactant)RAphotodissocn van der Waals cluster; iodine rare gas cluster photolysis; vibrational state distribution cluster photolysis; complex van der Waals photodissocntext::journal::journal article::research article
