Low‐Frequency Raman Spectra of Natural Pyrrhotites: Polarization Dependence for Its Lattice Modes

Journal of Raman Spectroscopy, EarlyView.
The present study found low‐wavenumber Raman modes of pyrrhotite Fe1‐xS at ~68, ~87, ~117, and ~230 cm−1 for the first time, thanks to a lab‐built Raman spectrometer, in which the optical path of the incident laser was purged by Ar gas. The sufficiently high signal‐to‐noise and signal‐to‐base ratios enabled us to obtain the polarization dependence of ...

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.

Microplastics Identification in Remote Aquatic Environments Using Raman Spectroscopy: A Case Study for Mt. Tymfi's Alpine Lake

Journal of Raman Spectroscopy, EarlyView.
This work contributes to the literature on the detection of MPs in Greece, proposes a method for MPs extraction in remote environments taking into account fieldwork constraints of an expedition in the Greek Alps, and takes a step forward in MPs analysis by Raman spectroscopy. ABSTRACT Water samples from the alpine lake of Mt.

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 ...

Terrestrial Lithium Exploration Adapted From Raman Diagnosis of Phyllosilicates for Mars

Journal of Raman Spectroscopy, EarlyView.
Analyses using a benchtop Raman instrument at the University of Aberdeen and a prototype instrument for remote deployment on Mars based at the University of Leicester successfully discriminated between four varieties of mica (possibly lithium‐rich rocks).
