Abstract :
We report the development of a new molecular beam source of hydroxyl radicals. An electrostatic hexapole focuses and state-selects radicals produced in a corona discharge. Routinely generated beams of OH have the following important characteristics: high purity with only one rotational state populated, intensities exceeding 1013 molecules cm−2 s−1, and narrow velocity distributions (Δv/v < 0.10).
