Energy Disposal in Reactions of Fluorine Atoms with Polyatomic Hydride Molecules as Studied by Infrared Chemiluminescence... 

The Infrared chemiluminescence technique has been pioneered by J. C. Polanyi (5-21). The University of Toronto group has concentrated on three-body reactions and more recently on reactions with vibratlonally and translationally excited reagents (14-21). At Kansas State University attention has been directed to reactions of F atoms with polyatomic hydrides (22-33) a large body of data has been obtained and information theory has been used for interpretation Other groups working in... 

On the other hand reactions of hydride radicals with each other lead to the formation of astrophysically important, but often non-polar molecules such as HCCH, H2CCH2, H3CCH3. Correspondingly HNNH, H2NNH2 and in particular HOOH and HSSH, which are all polar, may very well be detectable in interstellar space. Surface reactions of the hydride radicals with other radicals and molecular fragments produce more complex molecules. For example cyano-acetylene, HCC-CN may well have been formed this way. All detected interstellar polyatomic molecules can be explained this way (see Table-8) and some hitherto undetected, but important ones, can be predicted to exist in interstellar space. Their observation or absence in interstellar space may then in conjunction with laboratory results shed more light on possible chemical pathways.
