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