Validity of Forster Theory for Vibrational Energy Transfer in Low-Dimensional Water
Kinetics of vibrational Forster resonance energy transfer between the OH bonds of one-, two-, and three-dimensional liquid water is modeled by a Forster type of theory reflecting the excluded volume of intermolecular pairs of the bonds. When the size of excluded volume is comparable to so-called Forster radius of the bonds, the energy transfer kinetics is delayed from the prediction of Forster theory. The delay persists longer in the lower dimensions and results in the quantum yield of energy transfer to -deviate more largely from the prediction of FOrster theory. The excluded volume which is npt taken into account by Forster theory is a critical factor for the correct description of vibrational Forster resonance energy transfer particularly in low-dimensional water.
