Determination of thermodynamic properties of CrH,NiC and CuLi diatomic molecules with the linear combination of Hulthen-type potential plus Yukawa potential
In this work, we investigate the thermodynamic properties of and diatomic molecules with a linear combination Hulthen and Yukawa potentials in the presence and absence of magnetic and Aharanov-Bohm (AB) fields. The Schrödinger equation in 3D and 2D were solved using the Nikiforov-Uvarov (NU) method and the exact quantization rule (EQR) respectively. To determine the thermodynamic properties for the selected diatomic molecules, we first used the energy spectrum to evaluate the partition function and other thermodynamic functions such as entropy, Helmholtz free energy, internal energy and specific heat capacity. In addition, it is found that in the classical limit, the specific heat capacity saturates for large values of the principal quantum number, for the selected diatomic molecules at a fixed temperature except . Our results can be applied to molecular physics and chemical physics.
