Probing the Stability of Convolution Neural Networks and Support Vector Machines With Transmission Low Wavenumber Raman Spectroscopic Data

Journal of Raman Spectroscopy, EarlyView.
No spectral dataset is perfect, but how severely will imperfection cost you? This study finds that CNNs are more robust against spectral errors than SVMs, particularly with data that exhibits day‐to‐day calibration‐type errors. However, when no artefacts are present, the SVM produces the best model.

Resonance Raman Effect in Copper Carbonate Minerals Azurite and Malachite

Journal of Raman Spectroscopy, EarlyView.
This study employs Raman spectroscopy to examine the vibrational characteristics of azurite and malachite, specifically focusing on the stretching modes of the carbonate anion present in their structures. The results reveal a potential resonance Raman effect, characterized by an unexpected enhancement of the asymmetric stretching mode compared to the ...

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

Journal of Raman Spectroscopy, EarlyView.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration

The Pace di Siena and its Gems

Journal of Raman Spectroscopy, EarlyView.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.

Impact of Beam Profile on Raman Spectroscopy Measurements

Journal 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.

Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

Journal of Raman Spectroscopy, EarlyView.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...
