Abstract

Matrix isolation experiments have been done with samples containing $F_{2}$ and $X_{2}$ in argon, or $Ar/X_{2}$ and $Ar/F_{2}$ deposited simultaneously from separate vacuum systems, where $X_{2} = Cl_{2}, Br_{2}$, or $I_{2}$. In experiments where both $F_{2}$ and $Br_{2}$ or $I_{2}$ were mixed in one can, prior reactions resulted in deposition of a mixture of $XF, XF_{3}$, and $XF_{5}$ species, with the larger species favored with the heavier halogens. Mercury are photolysis of these matrices produced several new bands in the IR spectra, some assignable to the known $XF, XF_{3}$ and $XF_{5}$ species, indicating definite F atom migration within the matrix. New bands also appear on photolysis or on subsequent thermal cycling, which can be assigned to the new interhalogen species $XF_{2}, X_{2}F$, and $X_{2}F_{2}$.
