Precise calculations on spectroscopic parameters of diatomic molecules using a novel potential energy function

YU Chang-feng ZHU Chang-jun LIU Dai-zhi 1.Department of Physics,School of Sciences,Xi'an Polytechnic University,Xi'an 710048,P.R.China 2.Section 602,Second Artillery Institute of Engineering,Xi'an 710025,P.R.China  
A novel scheme for potential energy functions of diatomic molecules is derived using a function with phase factors. Six kinds of potential curves of common shapes are obtained by adjusting the phase factors.Spectroscopic parameters of the ground states for ten kinds of molecules are calculated using the potential energy functions.The results agree well with experimental data.
【Key Words】: potential energy function force constants spectroscopic parameters diatomic molecules
