We studied exact solutions and spectrum analysis of the pseudoharmonic oscillator in the presence of θ ‐dependent scalar potential and the sum of two vector potentials Dirac magnetic monopole and Aharonov‐Bohm field. The effect of the Dirac magnetic monopole ( g ), Aharonov‐Bohm field (ℱ) , the dissociation energy of diatomic molecules ( D e ), equilibrium intermolecular separation ( r e ), and the reduced mass ( μ ) on the energy spectrum for some diatomic molecules (CO, NO, N 2 , CH, H 2 , and ScH) are analyzed. We compared our results with theoretical experiments of pseudoharmonic oscillator potential in a molecular system.
