Abstract

The purpose of this study was to calculate the radia-
tive parameters (Einstein coefficients of spontaneous radia-
tion, oscillator strengths for absorption, Franсk — Condon

lifetimes of excited electronic state. The vibrational energies
and the wave functions are found as a result of numerical
solving of the radial wave equation based on potential ener-
gy curves constructed in the present work. We compared the
calculated energies with experimental values and for the first
time obtained the radiative lifetimes
