Abstract : A study of the mercury-photosensitized decomposition of ammonia, both with pure ammonia and with propane added as a scavenger for hydrogen atoms, suggests that the quantum yield of the primary decomposition into H and NH2 is much less than unity at 33 C and rises with increasing temperature. The interaction of ammonia-propane mixtures with Hg atoms cannot be explained in terms of simple competitive quenching; a tentative mechanism involving a long-lived Hg propane complex and Hg atoms has been suggested. A temperature dependence in the relative quenching rates of C3H8 and C3D8 has also been observed. (Author)
