Abstract: | The magnetic dipole transition I(52P-52P) at 1.3152 μm is shown to be enhanced by collisions of the metastable iodine atoms with the parent RI molecules CF3I, C2F5I, i-C3F7I and n-C3F7I. The enhancing mechanism is exciplex emission of the RI·I(52P) molecule at 1.3 μm, with different rates for each iodide. The influence of this effect on the measurement of the quantum yields to I(52P) and of the respective reaction rates by infrared fluorescence is discussed. |
