Paper Abstract

Hexapole state-selection and orientation of parent molecules is combined with two-dimensional ion imaging of photofragments to study the direct photolysis of deuterated methyl iodide molecules (CD3I). These two techniques allow us to create an essentially single quantum state-selected beam of oriented molecules, which are subsequently photodissociated, and to measure the final state-, velocity-, and angle-resolved recoil distribution of fragments. For the prompt dissociation of CD3I at 266 nm the angular recoil distribution reflects predominantly the initial spatial orientation of the state-selected parent. The dependence of the orientation of the parent as a function of the orientation fieldstrength has been investigated and the three-dimensional recoil distributions of fragments are compared with theoretically calculated distributions.
