摘要： A four-parameter nonlinear model is introduced to the description of the X-Y stretching modes of XY6 octahedral molecules in the electronic ground state. We here only apply it to the calculations of S-F stretches of SF6 molecule. The model calculations appear to describe the observed data well, and predict some new vibrational bands at accurate energies not yet observed.
