The assignment of the overtone and combination bands which appear in the infrared spectra of fibrous proteins between 4200 and 5500 cm−1 is discussed on the basis of the normal vibrations of an isolated —CO.NH— group. Equations relating the degree of molecular orientation in a protein fibre with transition moment direction and dichroic ratio are derived and the assignment of the transition moment direction associated with certain vibrations is considered.
