Upconversion time-stretch infrared spectroscopy [PDF]
Light: Science & Applications, 2023 We develop upconversion time-stretch infrared spectroscopy, which enables high-speed and high-resolution broadband mid-infrared spectroscopy with over 1000 spectral elements at a rate of more than 10 MSpectra s−1.

Infrared Spectroscopy—Mid-infrared, Near-infrared, and Far-infrared/Terahertz Spectroscopy
Analytical Sciences, 2021 This article aims to overview infrared (IR) spectroscopy. Simultaneously, it outlines mid-infrared (MIR), near-infrared (NIR), and far-infrared (FIR) or terahertz (THz) spectroscopy separately, and compares them in terms of principles, characteristics, advantages, and applications.

Infrared Difference Spectroscopy of Proteins: From Bands to Bonds
Chemical Reviews, 2020 Infrared difference spectroscopy probes vibrational changes of proteins upon their perturbation. Compared with other spectroscopic methods, it stands out by its sensitivity to the protonation state, H-bonding, and the conformation of different groups in ...
