New Optical Formulae for Thin Films Boost Accuracy for Real-World Applications

6 days ago | spectroscopyonline.com | Jerome Workman

New formulae improve thin-film analysis by accounting for wedge geometry and absorbing substrates. Enhanced models show higher accuracy over a broad spectral range, particularly in UV-vis-NIR. A publicly available toolkit in Python and MATLAB supports the practical application of the findings. The study emphasizes a trade-off between computational efficiency and optical model accuracy.
Bruce R. Kowalski: The Maverick Mind Behind Chemometrics

6 days ago | spectroscopyonline.com | Jerome Workman

Bruce R. Kowalski (1942–2012) is widely regarded as a founding figure in the field of chemometrics. His pioneering work in multivariate statistics, pattern recognition, and data processing enabled chemists to interpret complex chemical data more effectively and reproducibly.
Cracking the Martian Code: Using Raman Spectroscopy and Chemometrics to Reveal Hidden Organic Clues in Meteorites

1 week ago | spectroscopyonline.com | Jerome Workman

Raman imaging with PCA and MCR-ALS enabled non-destructive identification of organic compounds in a Martian meteorite. Spectroscopic analysis preserved meteorite integrity by avoiding surface alteration or polishing. A Renishaw inVia spectrometer with controlled laser power and daily calibration ensured precise, artifact-free Raman measurements. This spectroscopic approach supports biosignature detection in Martian samples and future planetary return missions.
Raman Reveals Rare Ribbeck Meteorite Clues About Ancient Solar System

1 week ago | spectroscopyonline.com | Jerome Workman

Raman spectroscopy and XRD confirmed Ribbeck's mineralogy, including pure enstatite, albite, and forsterite phases. Spectroscopic analysis highlights Ribbeck as a pristine aubrite with minimal Earth-based alteration. Rare metallic and sulfide inclusions, revealed via EDS, formed under highly reduced, oxygen-depleted conditions. Spectroscopy supports Ribbeck’s magmatic and metamorphic history, refining insights into aubrite evolution and Solar System formation.
Ancient Meteorite Reveals Space Weathering Secrets Through Cutting-Edge Spectroscopy

1 week ago | spectroscopyonline.com | Jerome Workman

Seven spectroscopy techniques, including vis-to-MIR reflectance and Raman, were used to analyze CM2 meteorite NWA 12184. Spectroscopy identified native minerals like phyllosilicates and olivine, distinguishing them from terrestrial weathering products. Ion irradiation and spectroscopic monitoring showed spectral darkening, reddening, and hydration band shifts due to surface amorphization.
