Exploring the Unique Capabilities of Infrared and Terahertz Spectroscopy in Material Science
Introduction to Infrared & Terahertz Spectroscopy Infrared (IR) and Terahertz (THz) spectroscopy are powerful analytical tools that measure the absorption of light in the IR or THz portion of the electromagnetic spectrum. IR spectroscopy measures the absorption of light in the mid-infrared range, while THz spectroscopy measures the absorption of light in the far-infrared range. IR and THz spectroscopy can be used to identify, quantify, and characterize chemical compounds. IR spectroscopy works by measuring the amount of energy absorbed in particular regions of the infrared spectrum. The energy absorbed is related to the presence and concentration of certain compounds in the sample. The IR spectrum of a sample is a fingerprint that can be used to identify the components of the sample. This technique is especially useful for identifying and quantifying organic compounds. THz spectroscopy works by measuring the amount of energy absorbed in the far-infrared portion of the spectr...
