报道了固相短链肽序列在77和298 K下的太赫兹（THz）吸收光谱和中子振动光谱。我们证明了这些系统在1-15 THz（33-500 cm（-1））光谱范围内存在高度的光谱和结构信息。每个系统的不同光谱特征的密度和唯一性表明，序列相关的结构信息可以使用量子力学固态建模和理论从这些光谱中提取。出版社：Elsevier Science B. V.
Terahertz (THz) absorption and neutron vibrational spectra for solid-phase short-chain peptide sequences at 77 and 298 K are reported. We demonstrate that a high degree of spectral and structural information exists for these systems in the 1-15 THz (33-500 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.
