Simplified models for vibrational energy transfer in proteins

We consider the transfer of vibrational energy in proteins and derive a simplified model for the resonant energy exchange between different vibrational modes. We use the parameters of an earlier study [K. Moritsugu, et al., Phys. Rev. Lett. 85 (2000) 3970 ] to compare our predictions with the results of the molecular dynamics simulations, and reveal an excellent agreement.
