Comprehensive vibrational analysis of CO2 based on a polyad-preserving model

摘要: We present a polyad-preserving algebraic approach to molecular structure and, as an application, we fit the model parameters reproduce extensive experimental data set of vibrational energies carbon dioxide in its ground electronic state. The includes levels with angular momentum l = 1,...,6 and some recently obtained term values that have not been previously considered. results are close uncertainty compare making use three most common polyad schemes can be found literature for this species.
