Intermolecular vibration–vibration energy transfer in solution: Hydrogen fluoride in water

An explicit formulation for intermolecular vibration–vibration (VV) energy transfer is applied to the energy transfer between a hydrogen fluoride (HF) molecule and the symmetric, antisymmetric and bend overtone vibrations of its hydrogen-bonded neighboring water molecule in aqueous solution. The results are analyzed in terms of coupling factor strength and resonance issues. The validity of the point dipole approximation is also investigated.
