In this work, the radial Schrödinger equation is solved with the improved Tietz oscillator in the presence of an external magnetic and Aharonov-Bohm (AB) flux fields. By employing the proper quantization rule, analytical equation for bound state energy levels was derived within the framework of Pekeris-type approximation scheme. The expression for the energy levels was used to generate numerical data for some diatomic substances including HF (X 1Σ+), HCl (X 1Σ+), HI (X 1Σ+), CO (X 1Σ+), MgH (X 2Σ+), ICl (A 3Π1), K2 (a3Σu+), 7Li2 (a3Σu+), BrF (X 1Σ+) and BCl (X 1Σ+) molecules. In the absence of the external fields, the mean absolute deviation of the energy levels from experimental data of the molecules are 3.3494%, 2.9210%, 2.8613%, 0.3985%, 4.0886%, 0,9203%, 1.7691%, 0.4850%, 1.0628%, and 0.9010%. The study further reveal that in the absence of the external fields, the obtained energy levels are degenerate. However, if the fields are maintained at about 10 μT, the resulting energy of the molecules is nondegenerate. The results obtained are in good agreement with available literature on diatomic systems.
