Abstract
The discrete self-trapping (DST) equation describes a coupled system of anharmonic oscillators that can be quantised in a remarkably simple manner. Here the DST system is used to describe the relationship between quantum and classical descriptions of local modes of vibration in a molecule.Keywords
