The Photolysis Of Propane At 123.6 Nm, James H. Vorachek, Robert D. Koob

Office of the Provost Scholarship

Propane has been photolyzed at 123.6 nm, in the presence and absence of O₂, at pressures from 2–380 Torr. All products except ethane exhibit a pressure dependence which is attributed to secondary dissociation of the primary fragments, H₂, CH₄, C₂H₄, and C₃H₆. It is assumed that the range of energies carried by these fragments is broad enough that some will not dissociate even at low pressures while others of the same species cannot be stabilized even at high pressures. An internally consistent analysis rationalizes the entire …
