Abstract :
The shifted Tietz–Wei (sTW) oscillator is as good as traditional Morse potential in simulating the atomic interaction in diatomic molecules. By using the Pekeris-type approximation, to deal with the centrifugal term, we obtain the bound-state solutions of the radial Schrödinger equation with this typical molecular model via the exact quantization rule (EQR). The energy spectrum for a set of diatomic molecules (NO(a 4 Π i ) , NO(B 2 Π r ) , NO(L ′2 ϕ) , NO(b 4 Σ − ) , ICl(X 1 Σ + g ) , ICl(A 3 Π 1 ) and ICl(A ′3 Π 2 ) for arbitrary values of n and ℓ quantum numbers are obtained. For the sake of completeness, we study the corresponding wavefunctions using the formula method.
