Modular and Automated Workflow for Streamlined Raman Signal Analysis

Journal of Raman Spectroscopy, EarlyView.
This study presents an automated workflow for preprocessing and analyzing Raman spectroscopy data, addressing key challenges such as noise suppression, baseline correction, and peak fitting using Voigt profiles. The method is validated on both synthetic and experimental spectra, demonstrating improved spectral fidelity and peak detection for biomedical

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 ...

Experimental and Computational Raman and SERS Study of Acid Blue 113

Journal of Raman Spectroscopy, EarlyView.
The vibrational features of AB‐113 were investigated through experimental and theoretical analyses. SERS spectra showed enhanced responses under resonant excitation, especially at 532 and 632.8 nm, enabling identification limits as low as 1.0 × 10−8 mol L−1.

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

Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

Journal of Raman Spectroscopy, EarlyView.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...

Progress in Resource Evaluation Using a Handheld Raman Instrument Developed for Astronaut Missions

Journal of Raman Spectroscopy, EarlyView.
Analogue studies were undertaken using a prototype, handheld Raman spectrometer (developed for astronaut usage on the moon) to collect data that would indicate the presence of water and help develop the technology to search for valuable trace elements (such as lithium and caesium).
