The principal features of Infrared absorption of the protein molecules are anomalous red shifts of the main peaks and increases of intensity of the anomalous bands with decreasing temperature which are proved by experiments. We think that these anomalous phenomena are caused by the self-trapping of amide-I vibrational quantum (vibron). We thus proposed a soliton model of the vibrons interacting with optical vibration of amino acid residue (phonon) to study theoretically these phenomena. We find farther out the exponential-reductions of the intensity of the anomalous bands in the infrared absorption with increasing temperature in the protein molecules by using this model. This shows that the living things including human beings and animals can absorb more much infrared lights at low temperature than that at high temperature.
