| Abstract: | A direct photoionization technique is proposed to measure the dissociation rates of overexcited polyatomic iodides in the ground electronic state. Measurements are carried out in a molecular beam, which enables one to avoid thermal drift of the reagents and thus widen the range of the measurements toward longer lifetimes. Here the first results are reported of measurement of unimolecular decay rates of (CF3)3CI whose overexcitation in the electronic ground state has been effected by the IR multiple-photon excitation technique. |
