metadata.value: In this paper we study vibrational relaxation of CO molecules with excited electronic states. We consider
  three electronic terms and account for V V exchanges of vibrational energy within each electronic term,
  V T transitions of vibrational energy into translational and V E exchange of vibrational energy between
  electronic terms. The initial vibrational state of the gas is strongly non-equilibrium. The effect of V E
  exchange on the vibrational relaxation of CO molecules is evaluated for different kinds of initial vibrational
  distributions, in particular, the Treanor and Gordiets ones generalized for gases with electronically excited
  states. The set of equations of state-to-state vibrational kinetics coupled to the gas-dynamic equations
  is solved numerically in the zero-order approximation of the Chapman-Enskog method for the case of
  spatially homogeneous relaxation. The following results were obtained: neglecting V E exchanges leads to
  an incorrect assessment of the numerical density for each electronic level, however, the error is small for
  the ground electronic state. It is shown that V E exchanges qualitatively affect the time dependence of the
  vibrational temperature. Refs 17. Figs 5.
