WebThe soliton is formed by self-trapping of the amide I energy by the induced lattice distortion. [1] [2] In quantum biology, the Davydov soliton (after the Soviet Ukrainian physicist Alexander Davydov) is a quasiparticle representing an excitation propagating along the self-trapped amide I groups within the α-helices of proteins. WebFeb 18, 2024 · Exciton formation leads to J-bands in solid pentacene.
