Molecular Spectroscopy Workbench: Thin-Film Filters for Raman Spectroscopy (PDF)

The Infrared and Raman Discussion Group’s 238th meeting on December 21 will feature the IRDG-Coblentz Lecture, two award presentations, and talks spanning clinical Raman, SERS, and ultrafast spectroscopy.

Organized by CPACT, the April 27 to 29 meeting at the Marriott Pittsburgh City Center will bring together scientists, engineers, and vendors across the process industries, with keynotes on PAT, Raman, and NIR applications and an abstract deadline of December 7, 2026.

Spectroscopy's editors gather 143 evergreen articles from 2026, including tutorials, terminology guides, technique reviews, application surveys, peer-reviewed research and the magazine's long-running columns, and organize them by subject so readers can build lasting knowledge one topic at a time.

A Q&A interview from SciX explored a porous-particle Raman platform became an alternative to SERS, and why AI could unlock biochemical meaning in vibrational spectra.

Jürgen Popp, winner of this year’s Ellis R. Lippincott Award, discusses the regulatory, cost, and workflow hurdles of moving Raman spectroscopy into hospitals.

This column shows that a Raman plate reader paired with partial least squares regression can simultaneously quantify glucose, fructose, sucrose, and ethanol in yeast fermentation samples, using turbidity-matched calibration standards to correct for yeast-induced turbidity, and offers a rapid, label-free, high-throughput method for tracking sugar consumption and ethanol production in strain screening, media optimization, and process development.

Mammograms can find breast microcalcifications but can’t tell whether they are likely benign or malignant.

In a SciX interview, Marc Porter covered a lot of ground, from a student-driven pivot into immunoassays to a baseball analogy for Stokes and anti-Stokes scattering, and shares the open questions he is still chasing.
