Molecular Study on the DKP Equation in (1 + 3) Dimensions with Isotropic Oscillator plus Inverse Quadratic Potential in Non-Commutative Space

The non-commutative DKP equation in (1 + 3) dimension with isotropic oscillator plus inverse quadratic potential are solved within the Nikiforov-Uvarov method. The energy eigenvalues equation and the eigenfunctions are obtained. The energy shift arises as a result of space non-commutativity is evaluated within the ambit of perturbation theory. Using the molecular constants for some molecules, the effect of non-commutative space on the behaviour of some molecules are studied. The results revealed that the space noncommutativity modify the bound state energy levels significantly for all the molecules as it was seen that the energy shifts increases for any increase in perturbation parameter \(\uptheta\) $\mathrm{\theta }$ .
