Abstract
$^{2}A^{\prime\prime}$ phenylperoxyl radicals, $\chem{C_6H_5O_2}$, have been generated in a cryogenic Ar matrix. In a two pulse experiment, phenyl radicals, $\chem{C_6H_5}$, are generated via pyrolysis of phenyliodide in Ar through a hyperthermal $\chem{SiC}$ nozzle and deposited on a $\chem{CsI}$ window at 20 K; a second valve deposits a layer of $\chem{O_2}$ in Ar on top of the phenyl radicals. The process is repeated and phenylperoxyl radicals are formed in the matrix. The matrix is analyzed with an IR spectrometer to identify vibrational frequencies of the radical.
