This work uses findings to generate a set of simple dimensionless equations, one of which yields the maximum amplitude of oscillation of the system at dissociation. The equations incorporate experimental data which are widely available and a set of such data for simple molecules is presented at the conclusion of the work. The simplicity of the equations developed is exemplified by that for the maximum amplitude of oscillation, Xe, when the system encounters an incoming photon possessing the magnitude of the dissociation energy, De, of the molecule, i.e. (Xe/R) = 2 sqrt(De.Be)/We.
Here, R is the bond length, We, the energy of the photon which raises the system from the ground state to the first excited state, and Be is the bond rotational constant. It is suggested that the simple expressions developed here have their application in the violent events associated with dissociation in shock waves and/or high energy particles emanating from stellar collapse and hence may be of utility in these areas of astrophysical modelling.

Chapter Summaries
- Introduction: This chapter provides an overview of the quantum harmonic oscillator model for diatomic molecules, highlighting its limitations and contrasting it with the Morse potential model. It also introduces the concept of photons as a source of excitation and dissociation.
- Analysis: This chapter presents the derivation of the energy eigenstates for the diatomic molecule model developed in the previous work. It discusses the role of photons in exciting the molecule and the relationship between the potential energy of the bond and the energy of the incoming photon.
