Abstract
The broadening of molecular spectral bands in hydrogen bonded systems is calculated for a simple model of the hydrogen bonded molecule on the assumption that it is due to the precession of coupled anharmonic vibrations. The approximate classical mechanics of such a generalized system is developed in terms of known results in the theory of non-linear mechanics. It is shown that when reasonable molecular parameters are substituted into the calculated broadening one obtains values consistent in all respects with the experimental data.
