The classical effects of rotation on vibrational energy transfer have been analyzed using a model based on H2O and its deuterated analogs. This model examines the coupling of the two stretching modes when rotation in the plane is allowed but the bending mode is frozen. It is found that the effects of rotation can be significant but the nature of the effects depends on the details of the system. For example, an angular momentum of 30 ℏ greatly increases energy transfer for H2O but decreases energy transfer for D2O. An explanation for this difference in behavior is derived from the effect of rotation on the 1 : 1 vibrational resonance.
