Title: Infrared spectroscopic observation of the stabilized intermediate complex FO{sub 3} formed by reaction of mobile fluorine atoms with ozone molecules trapped in an argon matrix

Abstract

Chemical reaction of F atoms with O{sub 3} molecules in a solid argon matrix was studied with FTIR spectroscopy. Fluorine atoms were generated by UV photolysis of F{sub 2} molecules in dilute solutions of F{sub 2} and O{sub 3} in solid argon. The FO-O{sub 2} complex is observed for the first time as an intermediate product by reaction of mobile F atoms with isolated ozone molecules. The observed complex is characterized by two intense absorption bands at 1522 and 968 cm{sup {minus}1}. Use of isotopic mixtures {sup 16}O/{sup 18}O provides strong evidence for assignment of these bands to the O-O stretch and F-O stretch fundamentals of the complex, which are red-shifted by 34 and 61 cm{sup {minus}1}, respectively, from the corresponding values for O{sub 2} and FO. Photolysis at 532 nm leads to decay of the FO-O{sub 2} complexes and to the appearance of isolated free FO radicals.
