Low-Frequency Parametrization of Hydrogen Bonding

Abstract
We review the model of the hydrogen bond developed by Lippincott and Schroeder and discuss the frequency range in which it is valid, specifically in the optical and near infrared range. We then show why and how to modify the Lippincott and Schroeder formulate to apply to the far infrared and lower ranges. The contrasts between the old and modified systems, particularly with respect to the effective force constants are worked out and plotted for an example.
