Abstract
An anharmonic potential function proposed by Parr and Brown in a form suited to symmetric linear triatomic molecules has been tested against experimental spectroscopic data for CO2 and CS2. The potential function, with only four or five adjustable parameters, gives a good fit to the spectroscopic data and models fairly well the general quartic force field of CO2, which contains 12 independent force constants.Keywords
