✦ Synopsis

Abstract

Resonance vibrational interactions of amide I for the parallel‐chain pleated‐sheet structure have been treated on the basis of the perturbation theory in a dipole–dipole approximation. The infinite sheet and finite fragments of different types have been considered. The possibility of experimental observation by infrared spectra of parallel‐chain pleated‐sheet fragments in globular proteins is discussed.

## Abstract Amide‐I and II vibrations of α‐helix have been treated on the basis of the perturbation theory in a dipole–dipole approximation. The infinite helix and its finite fragments have been considered as models. The calculated infrared spectra for the infinite helix are in good agreement with
