Abstract

The photodissociation dynamics of methyl iodide following ultraviolet excitation was studied at 333 nm, the longest wavelength at which methyl iodide photolysis was examined to date, in which it was determined that the I/I branching ratio as a function of polarization of the photolysis radiation. This study presented insights into the nature of the transitions that carry oscillator strength in this region and implied that direct excitation of the 3Q0 state may be significant at wavelengths greater than or around 300 nm used in the photolysis of methyl iodide. Moreover, this study provided information about the location of the 3Q0-1Q1 conical intersection, a crucial parameter to the accurate theoretical modeling of the photodissociation process.
