LifsonRoig model is a helix-coil transition model applied to the alpha helix-random coil transition of polypeptides and is the only analogous transfer-matrix methods in polymer science that have also been applied to nucleic acids and some type of polymers.
The ZimmBragg and LifsonRoig models are but the first two in a series of analogous transfer-matrix methods in polymer science that have also been applied to nucleic acids and branched polymers.
