Spectroscopy Top 10 Articles of the Month

The following articles are the 10 most accessed digital object identifier (DOI) manuscripts for Spectroscopy and LCGC International during March, 2026. Each article has been selected based on the number of successful DOI page views by readers as reported by [email protected]. The articles showcase key developments and insights in spectroscopy and chromatography. Spectroscopy covers the main topics of electronic spectroscopy, vibrational spectroscopy, magnetic resonance, imaging techniques, atomic spectroscopy, and data analysis and integration. LCGC covers most aspects of separation science.

This month we highlight articles from the ever-popular Spectroscopy columns and feature articles: IR Spectral Interpretation Workshop, Lithium-Ion Battery Analysis, the Latest Research Applications Using FT-IR Spectroscopy, Interpretation of the Raman Spectrum of Proteins, Molecular Spectroscopy Workbench, Enhancing Extractions by Salting Out, Chemometrics in Spectroscopy, and Field-Deployable Liquid Chromatography for Environmental Studies. We hope you enjoy reading these most accessed DOI-registered technical articles from March; the DOI links and summaries for each of the 10 articles is given below.
