Impact of Beam Profile on Raman Spectroscopy Measurements

open access: yesJournal of Raman Spectroscopy, EarlyView.
Characterisation and optimisation of the laser beam profile in Raman spectroscopy is critical to ensure accuracy and reproducibility of measurements. The laser beam size and profile have a significant effect on the axial resolution, energy distribution on the sample, focal spot size and excitation volume.

Modular and Automated Workflow for Streamlined Raman Signal Analysis

open access: yesJournal 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

open access: yesJournal 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

open access: yesJournal 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.
