Raman Spectroscopy from Laboratory and Proximal to Remote Sensing: A Tool for the Volcanological Sciences

Here we explore and review some of the latest ideas and applications of Raman spectroscopy to the volcanological sciences. Firstly, we provide a brief overview of how Raman spectral analysis works and how spectra from silicate glasses are interpreted. We then look at specific applications of Raman spectral analysis to the volcanological sciences based on measurements on and studies of natural materials in the laboratory. We conclude by examining the potential for Raman spectral analysis to be used as a field based aid to volcano monitoring via in situ studies of proximal deposits and; perhaps; in remote sensing campaigns

Raman Spectral Analysis

AbstractCopolymeric structures with compositional gradient were produced by “in situ” radical polymerization -in water and with redox initiation- of acrylic acid (AA) and 2-hydroxyethyl methacrylate (HEMA) in the presence of an inhibitor (hydroquinone). The inhibitor has a key role in controlling the mixing of precursor solutions because it produces a retardation of the polymerization. Raman spectral analysis confirmed the changes in the composition along the long axis of the produced cylindrical materials. Compression tests were also performed, exhibiting the gradient and reference material’s unique properties, which were well correlated to the compositional pattern.

Raman Spectral Analysis

ABSTRACT Organic single crystal of Phthalic Anhydride (PA) was successfully grown by slow evaporation method. The structure of the grown crystal was confirmed by X-ray diffraction analysis. FT-IR, and FT-Raman spectral analysis of the crystalline samples reveal that the crystalline sample consists of all functional groups. The placement of protons was identified from H1-NMR spectral analysis. UV-Visible and photoluminescence spectral analyses were carried out for the grown crystals. The thermal behavior was studied with TGA-DTA analyses. The existence of second harmonic generation (SHG) signal was observed using Nd:YAG laser with a fundamental wavelength of 1064 nm.
