Correlation among parameters of the extended-Rydberg potential energy function

Abstract

This paper reports a remarkable correlation among parameters of extended-Rydberg potential function by recasting the Morse potential in the form of extended-Rydberg function via the application of infinite series expansion to the exponential terms of the Morse function. By using linear regression, a reasonable band that encompasses 90% of the diatomic combination given by Huxley and Murrell [J. Chem. Soc. Faraday Trans. II 79 (1983) 323] is furnished in a plotted characteristic map. © 2005 Springer Science+Business Media, Inc.
