Approximation methods for the calculation of force constants of a general valence force field in polyatomic molecules - a review
TL;DR: A survey of the various approximation methods for the calculation of force constants in polyatomic molecules using a general valence force field model can be found in this article, where the mathematical basis of these solutions is studied in detail with a view to giving their physical properties, significance and hence the limitations in their practical application.
