This mini-tutorial explores how data preprocessing (DP) transforms raw FT-IR ATR spectra into meaningful, reliable inputs for chemometric modeling. Readers will learn about key DP methods: normalization, scatter correction, centering, scaling, and baseline correction, and how proper selection of these techniques improves accuracy, reproducibility, and interpretability in infrared spectroscopic analysis.

Fourier transform infrared (FT-IR) spectroscopy is a versatile, non-destructive analytical tool used to characterize molecular structures, monitor chemical reactions, and quantify analytes in diverse materials. This mini-tutorial reviews fundamental principles, key operational modes, and practical examples across environmental, biomedical, and industrial applications. Readers will review and learn how to optimize FT-IR methods, interpret spectra, and avoid common pitfalls in data collection and processing.

In this continuation of our discussion with Sergei Kazarian and Bernadette Byrne, they address how recent advancements in FT-IR imaging are set to propel the biomedical and pharmaceutical industries forward.

Albert A. Michelson

This video in the Icons of Spectroscopy series highlights the life and scientific achievements of Albert A. Michelson, the first American Nobel Laureate in the sciences. It traces his journey from his early years in the American West and his education at the U.S. Naval Academy to his groundbreaking experiments measuring the speed of light. We explore his invention of the Michelson interferometer, its role in the famous Michelson–Morley experiment, and its lasting influence on modern optical and spectroscopic methods, including astronomy.

The miniaturization of spectroscopic instruments has reached a remarkable milestone: wearable vibrational spectroscopy. Techniques such as Raman, surface-enhanced Raman scattering (SERS), infrared (IR), and functional near-infrared (fNIRS) spectroscopy are no longer confined to the laboratory bench—they now fit on our bodies, into household devices, and onto industrial equipment. These wearable devices promise continuous, real-time monitoring, offering molecular-level insights for personal health, household management, clinical care, and industrial applications.
