Abstract: The photodissociation of CF3I has been studied near 304nm. The partially resolved vibrational peaks in the I* and I channels reveal that the ν 2 umbrella mode of CF3 is preferentially excited. Besides, in the I* channel, the extra vibrational peaks assigned to the umbrella mode of CF3 from the hot band states of CF3I are also partially resolved. The E int/E avl shows a gradual increase as the state of CF3I changes from to . The anisotropy parameter is also obtained and discussed with the interrelation of the 3Q1, 3Q0, and 1Q1 potential energy surfaces. [Copyright &y& Elsevier]
