Abstract
$^{2}A^{\prime\prime}$ Allylperoxyl radicals, $\chem{C_3H_5O_2}$, have been generated in a cryogenic Ar matrix. In a two pulse experiment, allyl radicals, $\chem{C_3H_5}$, are generated via pyrolysis of allyliodide 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 allyl radicals. The process is repeated and allylperoxyl radicals are formed in the matrix. The matrix is analyzed with an IR spectrometer to identify vibrational frequencies of the peroxyl radical.
