Approximate resolutions of the Schrodinger theory applying the WKB approximation for certain diatomic molecular interactions.

ABSTRACT

CONTEXT The Analyzing of energetic bond spectra of diatomic compounds is crucial to understanding their qualities because it allows one to evaluate their attributes. Diatoms compounds' spectral properties and bound energies are presented in this study. These energies are found by solving the Schrodinger equation while making consideration of the employing of the Kratzer Feus potential. METHOD: This study focuses on the calculation of bound states for diatomic molecules using the WKB approximation. The final energy spectrum equation is utilized to compute the bound states of specific diatomic molecules for varying quantum numbers n and l through the utilization of the Mathematica software. The method produced the desired and anticipated results, as shown by a comparison of the eigenvalue results with earlier studies.
