OKORIE, U.S.; IKOT, A.N.; ONYEAJU, M.C.  e  CHUKWUOCHA, E.O.. A study of thermodynamic properties of quadratic exponential-type potential in D-dimensions. Rev. mex. fis. [online]. 2018, vol.64, n.6, pp.608-614.  Epub 05-Nov-2019. ISSN 0035-001X.  http://dx.doi.org/10.31349/revmexfis.64.608.

We solved the Schrödinger equation with Quadratic Exponential-Type Potential (QEP) model in D-dimensions using the Modified factorization method. The energy eigenvalues and total wavefunctions were obtained in a Gauss hypergeometric form. The thermodynamic properties including vibrational partition function, vibrational mean energy, vibrational mean free energy and vibrational entropy have been calculated for the electronic state of ( X 1 g + ) Rubidium ( R b 2) dimer. The QEP discussed can be applied extensively in Physics and Chemistry, especially in molecular dynamics.
