We propose an approximation scheme for the centrifugal term of our potential. In addition, an appropriate space-time of Duru-Kleinert transformation has also been performed to convert the radial path integral into a manageable one. Furthermore, two special cases are to be considered, the Pöschl-Teller type potential and the generalized hyperbolic potential, as well as by a combination of illustration and comparison of some diatomic molecules, namely (HCL, NiC, CO, and I2). It is found that this study is substantially marked, which communicated many important methods for solving the Schrödinger’s equation.enBound statesEnergy spectrumFeynman propagatorRadial propagatorSpace-time transformationWavefuctionsThe q-deformed modified Pöschl-Teller potentialArticle
