Abstract
The technique of the high-temperature flash pyrolysis has been used fo r the generation of jet-cooled methyl free radical beam. The result sh ows that Di-tert-butyl peroxide (DTBP) starts to decompose obviously a t temperature up to 900 K, and reaches the complete decomposition at 1 300 K. Short contact time of the seeded precursor molecules(4% mole DT BP in He) suppresses recombination of the methyl radicals. The major f ragments for the flash pyrolysis of DTBP are CH3COCH3 and CH3 . radica l.
