I've been trying to find the mechanism for the gas phase decomposition of hydrogen iodide:
$$\ce{ 2 HI (g) <=> H2 (g) + I2 (g)} $$
Anyone know of sources where I can get information on this? I found a 1927 paper in PNAS but wondered if there is anything more recent. This is the 1927 paper:
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1085202/
Proc Natl Acad Sci U S A. 1927 Oct; 13(10): 720–726. The Photochemical Decomposition of Hydrogen-Iodide; the Mode of Optical Dissociation
