We study the spectrum of polymethyl methacrylate (PMMA)—otherwise known as plexiglass—and the spectra of PMMA mixtures and copolymers.

A 3D printer can shorten the time to make prototype hardware for spectrometers from weeks to days—or less.

Handheld FT-Raman spectroscopy can complement GC–MS and IR in characterizing street drugs.

Andreas Riedo of the Physics Institute at the University of Bern, the 2023 winner of the Emerging Leader in Atomic Spectroscopy Award, is using laser ablation–desorption ionization mass spectrometry (LIMS) to chemically analyze complex mineral surfaces found in space exploration.

A new method based on singular value decomposition (SVD) applied to the denoising of the time-resolved spectral matrix (TRSM) made it possible to obtain kinetics data of the fluorescence band parameters of a 3-aminophthalimide spectrum in acetonitrile.
