Abstract

Terahertz (THz) absorption and neutron vibrational spectra for solid-phase short-chain peptide sequences at 77 K and 298 K are reported. We demonstrate that a high degree of spectral and structural information exists for these systems in the 1 THz to 15 THz (33 cm-1 to 500 cm-1) spectral range. The density and uniqueness of distinct spectral features for each system suggests that sequence-dependent structural information can potentially be extracted from these spectra using quantum mechanical solid-state modeling and theories.
