Triatomic Photofragment Spectra: I. Energy Partitioning in NO2 Photodissociation,

摘要: The photofragment spectrum of NO2 has been measured in the near ultraviolet at 28 810 cm−1. A molecular beam is crossed with brief pulses polarized laser light and measurements are made on distributions speed direction recoiling O NO fragments produced by photodissociation. average translational energy about 60% available energy. There least two prominent peaks distribution. We conclude that most likely correspond to nearly equal probability recoil fragment v=0 v=1 vibrational states. Such vibrationally excited photodissociation polluted atmospheres could perhaps react different rates than ground state fragments. positions widths indicate there a significant rotational Statistical direct models for partitioning briefly explored, their predictions compared wit...
