Far-IR/Terahertz Spectroscopy

In this interview, Peter Griffiths, 2023 recipient of the Ellis R. Lippincott Award, reflects over his storied career, as well as his most recent work, which focuses on measuring fine airborne particles within mining environments.

This interview with Young Jong Lee highlights the work he and his team have done to reinvent solvent absorption compensation (SAC), and the potential it has across multiple forms of spectroscopy.

This new terahertz method provides a theoretical reference for studying the relationship between biomolecules and water.

Terahertz time-domain spectroscopy was used to identify and analyze the low-frequency vibrational modes of three free anthraquinones, revealing the vibrational contributions of different atoms and groups.

A research team from Botswana International University of Science and Technology investigated 4-octyloxybenzoic acid, 4-decyloxybenzoic acid, and 4-hexylbenzoic acid liquid crystals, which highlighted the robustness of FT-IR and its potential in identifying materials with similar attributes.

The United States Pharmacopeia–National Formulary (USP–NF) has contributed to ensuring the quality of dietary supplements, foods, and medicines for more than 200 years. This overview explains the use of vibrational spectroscopy techniques in meeting USP–NF requirements and how the information is organized.

On the occasion of Spectroscopy’s 35th birthday, I thought it would be an interesting opportunity to consider the amazing explosion in light sources for spectroscopy over the last few decades.

Researchers at the National Institute of Standards and Technology (NIST) have created a technique that uses terahertz waves to measure structural properties in integrated circuits.
