A theoretical study of the O₂x³ g⁻- B³ u⁻photodissociation continuum

Franck-Condon densities qν,vn = [vertical line][integral operator]ψν(r)ψvn(r) dr[vertical line]2 for vn = 0 in the O2 Schumann-Runge photodissociation continuum have been calculated for realistic Klein-Dunham potentials. They are combined with measured values of absorption coefficient to study the variation of electronic transition moment in the continuum. For comparison, Franck-Condon factors have similarly been used in conjunction with measured oscillator strengths to show the behaviour of the transition moment for the vn = 0 progression of bands. It appears probable that the transition moment is continuous through the dissociation limit.
