Unveiling the Crystal Structure of Sanidine: A Polarized Raman and Ab Initio Simulation Exploration
Journal of Raman Spectroscopy, EarlyView.This study combines polarized Raman spectroscopy and ab initio calculations to assign theoretical vibrational modes to observed spectra. Polarized Raman spectra were collected in six geometries (40–1200 cm−1). Theoretical predictions via DFT show good agreement with experiments, though some discrepancies point to influences like trace elements and ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals
Journal of Raman Spectroscopy, EarlyView.This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Measurement of Lateral Resolution in Confocal Raman Spectroscopy Using Indium Arsenide Nanowires
Journal of Raman Spectroscopy, EarlyView.Lateral resolution is a key performance parameter for confocal Raman spectroscopy. We propose a protocol using an indium arsenide nanowire reference sample to quantitatively measure the resolution. The suitability of the method has been demonstrated through an international comparison with 15 participants. ABSTRACT Lateral resolution is a key figure of

Journal of Raman Spectroscopy, EarlyView.Endogenous constituents vary between fingernails of healthy, cardiovascular and diabetic participants. Raman spectroscopy yields a biochemical fingerprint of key endogenous constituents and disease‐related biomarkers. Combined with machine learning algorithms, Raman spectroscopy can classify healthy, cardiovascular and diabetic based on their Raman ...
