The thesis involved studying and calculating the spectral properties of the anthracene molecule and the naphthalene molecule in the stable state using quasi-experimental and comparative quantum programs and finding the spectral dissociation energies of both molecules by plotting their voltage by changing the length of the beam.

The study concluded that there were 66 vibration patterns of the anthracene molecule and 48 patterns of the naphthalene molecule, after studying the vibrations of the two sub-infrared particles of Hyper-Kim(Hyper ).
The researcher recommended the use of molecular modeling to study the spectral and thermal properties, and use (excitecl state) and using the abintio method.
