TLDR
The first use of pulsed terahertz spectroscopy to examine low-frequency collective vibrational modes of biomolecules was reported in this paper, which indicated that a large number of the lowfrequency collective modes for these systems are IR active.About:

Effective factors on twisted terahertz radiation generation in a rippled plasma
TL;DR: In this article, the effect of the orbital angular momentum of the Laguerre-Gaussian input laser beam on the vortex terahertz intensity was investigated. But the effect was not considered in this paper.

Terahertz Chiroptical Spectroscopy of an α-Helical Polypeptide: A Molecular Dynamics Simulation Study B
Jun Ho Choi,Minhaeng Cho +1 more
TL;DR: In this paper, using a molecular dynamics simulation method, infrared vibrational circular dichroism and vibrational optical rotatory dispersion spectra of a right-handed α-helix in the terahertz (THz) frequency range were calculated and Fourier-transformed to obtain THz absorption and optical activity spectra.
Journal ArticleDOI
Terahertz plasmonic phase-jump manipulator for liquid sensing
TL;DR: In this article, an ultraprecision THz sensor is achieved with direct phase readout capacity via combining steerable plasmonic resonance and attenuated total reflection, and the authors found that the reflected THz phase exhibits two entirely different jump responses to coupling gap.
Journal ArticleDOI
High efficiency terahertz generation in a multi-stage system.
TL;DR: The terahertz generation efficiency can be greatly enhanced by compensating the dispersion of the pump pulse after each stage, and the governing 2-D coupled wave equations in a cylindrically symmetric geometry are numerically solved using the finite difference method.
Journal ArticleDOI
Terahertz spectroscopy of biological molecules
TL;DR: In this paper, the absorption and refraction spectra for a number of amino acids, proteins and nucleic acids in the frequency range 0.1-3.5 THz were analyzed.

Structure of serum albumin.
Daniel C. Carter,Joseph X. Ho +1 more
TL;DR: This chapter provides an insight of the findings of past significant papers with the current knowledge of the recently determined high resolution X-ray structure of serum albumin and suggests that AFP may have a higher affinity for some unknown ligands important for fetal development.

Collective Variable Description of Native Protein Dynamics
Steven Hayward,Nobuhiro Go +1 more
TL;DR: The normal-mode refinement method of protein X-ray crystallography, which is developed based on the concept of the above important subspace, is discussed and indicates that most important conformational events are taking place in a conformational subspace spanned by a rather small number of principal modes.

Y. Cai,Igal Brener,John Lopata,J. D. Wynn,L. N. Pfeiffer,Jason Blain Stark,Q. Wu,X. C. Zhang,John F. Federici +8 more
TL;DR: In this article, free-space electro-optic sampling (FSEOS) was used with photoconducting antennas to detect terahertz (THz) radiation in the range of 0.1-3 THz.
