T. Donohue,John R. Wiesenfeld +1 more
TL;DR: In this paper, the branching ratios for formation of I (5'2P1/2) and I (2'5P3/2 ) following broad-band photolysis of a number of alkyl iodides and their fluorinated and deuterated analogs have been directly determined using time-resolved atomic absorption spectroscopy.

Polyhalide photofragment spectra. I. Two‐photon two‐step photodissociation of methylene iodide
TL;DR: In this article, a two-photon, two-step dissociation process of CH2I2 at a wavelength of 266 nm was investigated and energy distribution analysis indicated that the CH2 fragments are both translationally and internally excited, although quantitative estimation of their rovibrational excitation is complicated by the possibility of electronic excitation of one or more fragments in the two-phase process.
