 Title: MATRIX REACTIONS OF SULFUR ATOMS AND FLUORINE. INFRARED SPECTRA OF $SF, SF_{2}$ AND $SF_{3}$ IN SOLID ARGON. Creators: Hassanzadeh, P.; Andrews, Lester Issue Date: 1991 Publisher: Ohio State University Abstract: Sulfur vapor diluted with argon was passed through a microwave discharge and codeposited with argon-fluorine samples onto a CsI window at 12K. Variation of fluorine and sulfur concentrations over a wide range and sulfur-34 isotopic substitution provided a basis for identification of the $SF, SF_{2}$ and $SF_{3}$ transient species. The diatomic SF radical showed matrix site absorptions at 818.8 and $822.0 cm^{-1}$ for $^{32}S^{19}F$ and 809.9 and $813.1 cm^{-1}$ for $^{34}S^{19}F$. A similar site splitting was also observed for both symmetric and antisymmetric stretching vibrations of $SF_{2}$ at 832.5, 829.5 and 805.0, 804.6, $802.1 cm^{-1}$, respectively. The $SF_{3}$ radical revealed symmetric equatorial and anti-symmetric axial stretching vibrations at 843.8 and $681.8 cm^{-1}$, respectively. Sample annealing increased weak absorptions due to the higher fluoride species in the series including $SF_{4}$ and $SF_{6}$.
