Terahertz spectroscopy of short-chain polypeptides
نویسندگان
چکیده
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 ) 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.

Probing noncovalent interactions in biomolecular crystals with terahertz spectroscopy.
The far-infrared vibrational spectra of molecular crystals are dominated by intramolecular (internal) modes, which are also present in the isolated molecule, and noncovalent intermolecular modes, which arise from the interaction of the nearest neighbours (external modes). Conceptually this has long been understood and early experiments using Fourier transform infrared (FTIR) spectroscopy confir...
متن کاملTerahertz time-domain spectroscopy of amino acids and polypeptides.
Frequency-dependent absorption coefficients and refractive indices of amino acids (glycine and l-alanine) and polypeptides (polyglycine and poly-l-alanine) in the wavenumber region from 7 to 55 cm(-1) were measured by terahertz time-domain spectroscopy. A vibrational band was observed at 45.5 cm(-1) for polyglycine, which was assigned as an interchain mode. The reduced absorption cross sections...
متن کاملApplication of nanoporous silicon substrates for terahertz spectroscopy
Mid to far-infrared (terahertz) spectroscopy is a valuable tool for probing and characterizing macromolecular structures and motions of complex molecules, including low frequency vibrational and phonon modes in condensed phases. We describe here an improved and readily implemented method for performing terahertz spectroscopic measurements by using a nanoporous silicon substrate to capture and c...
متن کاملA Single-shot Terahertz Time-domain Spectroscopy Instrument for Intense Laser System
A single-shot terahertz time-domain spectroscopy method is developed using an echelon-pair. Terahertz waveform is encoded to a beamlets array by electro-optic effect, with a total time window of 37.7 ps and a time step of 94.3 fs. Comparing with spectral encoding methods, this technique directly encodes terahertz waveform to spatial resolution, which is more suited as a terahertz diagnosis for ...
متن کاملTime and Frequency Resolved THz Spectroscopy of Micro- and Nano-Systems
Terahertz technology [1], at present a dynamically developing field, was enabled by advances in ultra-short pulse lasers and semiconductor coherent sources in the frequency range of 1–50 THz. The extensive activities are focused on THz optics, spectrally bright sources, and detectors. The terahertz time-domain spectroscopy and terahertz imaging are main fields, where terahertz technology finds ...
