In our earlier papers we have proposed an analytically solvable model for thetwo state curve crossing problem which assumes the coupling to be a Dirac deltafunction. It is used to calculate the effect of curve crossing on electronicabsorption spectrum and Resonance Raman excitation profile for the case ofharmonic potentials. In this paper we have extended our model to deal with thecurve crossing induced dissociation cases. Our method is used in this paper tocalculate the effect of curve crossing induced dissociation on electronicabsorption spectrum and Resonance Raman excitation profile. In this paper, amodel consisting of a Harmonic oscillator and a Morse oscillator, coupled byDirac delta function, is solved.
