Abstract

The bromomethylperoxy radical, CH_2BrOO, has been generated in cryogenic matrices. Six fundamental bands for CH_2BrOO have been observed in an argon matrix at 5 K. The experimental frequencies (cm^(−1)) are: ν_4 = 1274.3, ν_5 = 1229.4, ν_6 = 1086.7, ν_7 = 961.8, ν_8 = 879.9, and ν_(10) = 515.4, two of which are detected for the first time. Ab initio calculations have been performed employing coupled-cluster methods. The experimental frequencies are shown to be in good agreement with the computation as well as the four bands (ν_4, ν_6, ν_7 and ν_8) observed by Huang and Lee in the gas phase.
