Internal vibration energy in polyatomic molecules containing chains of identical biatomic dipoles

Abstract

The quantum processes of excitation and vibrational energy transport that occur in polyatomic organic molecules under IR radiation are analyzed. The polyatomic organic molecules considered contain substructures with finite numbers of identical biatomic valence bonds, which play the role of antennas that trap and accumulate IR radiation. The result of this analysis can be used for determining the sequences of amino-acid residues in oligopeptides.
