Abstract

Dilute solid solutions of vinyl bromide in krypton and vinyl iodide in argon were photolyzed at 10 K with a medium pressure mercury lamp. When the vinyl bromide is photolyzed, both hydrogen bromide-acetylene complexes and bromoacetylene are observed as photolysis products. Kinetic analysis shows that the hydrogen bromide-acetylene complexes are the only primary photolysis products and that the bromoacetylene is formed by secondary photolysis of the hydrogen bromide-acetylene complexes. Similar results are observed for the photolysis of vinyl iodide, with hydrogen iodide-acetylene complexes the only primary products and iodoacetylene observed as a secondary photolysis product of the hydrogen iodide-acetylene complex. We present the first reported vibrational frequencies for the HI-acetylene complex.
