Reaction rate constant for radiative association of CF+ [PDF]

open access: yesThe Journal of Chemical Physics, 2016
Reaction rate constants and cross sections are computed for the radiative association of carbon cations (C+) and fluorine atoms (F) in their ground states. We consider reactions through the electronic transition 11Π → X1Σ+ and rovibrational transitions on the X1Σ+ and a3Π potentials.
