Effect of curve crossing induced dissociation on absorption and resonance Raman spectra: An analytically solvable model

• Model consisting of harmonic oscillator and Morse potential is solved.
• Dirac Delta function and Greens function is used.
• Absorption spectra and resonance Raman excitation profile is studied.

An analytically solvable model for the crossing of a harmonic and a Morse potential coupled by Dirac Delta function has been proposed. Further we explore the electronic absorption spectra and resonance Raman excitation profile using this model and found that curve crossing had significant effect on the resonance Raman excitation profile.
