Notes:
A method for the high-temperature generation of reactive species in supersonic molecular beams has been developed. Pyrolysis temperatures (25–1800 °C) can be maintained for longer than 100 h for extended experiments. Short contact time (≈10 μs) of the seeded (〈1 Torr partial pressure in 2 atm inert carrier gas) precursor molecules suppresses recombination of the product radicals. Number densities for radicals are estimated to be ≈1014 cm−3 at the sonic orifice with radical fluxes of ≈1016 s−1.
