摘要
Detailed measurements of infrared absorption and Raman scattering on crystalline acetanilide [${(\mathrm{C}{H}_{3}\mathrm{CONH}{C}_{6}{H}_{5})}_{x}$] at low temperature show a new band close to the conventional amide I band. Equilibrium properties and spectroscopic data rule out explanations based on a conventional assignment, crystal defects, Fermi resonance, and upon frozen kinetics between two different subsystems. Thus we cannot account for this band using the concepts of conventional molecular spectroscopy, but a soliton model, similar to that proposed by Davydov for $\ensuremath{\alpha}$-helix in protein, is in satisfactory agreement with the experimental data.
