Gas-phase laser Raman spectroscopy has recently been adopted to determine the concentrations of relevant gaseous species within the anode flow channel with high spatial and temporal resolution during operation at technically relevant operating conditions. The paper describes the configuration of an optically accessible SOFC, the laser system and optical setup for 1 D Raman spectroscopy as well ...

Raman spectroscopy for low-pressure or trace gas analysis is rather challenging, in particular in process control applications requiring trace detection and real-time response; in general, enhancement techniques are required. One possible enhancement approach which enjoys increasing popularity makes use of an internally-reflective capillary as the gas cell. However, in the majority of cases, su...

Infrared microspectrometry and Raman spectroscopy have been applied for examination of multilayer fragments of paints, for criminalisctic purposes. The study showed that under the conditions used, Raman spectra in the visible range (633 nm) provided data on the pigments but gave little or no information about polymers. Infrared was found to be good for characterising the polymer but failed to p...

We have developed a class of aperture coding schemes for Remote Raman Spectrometers (RRS) that remove the traditional trade-off between throughput and spectral resolution. As a result, the size of the remote interrogation region can be driven by operational, rather than optical considerations. In this paper we present the design of our coded-aperture standoff spectroscopy system as well as expe...

This article reviews recent advances in the Raman scattering study of oneand two-dimensional materials. The characteristic vibrational properties of the low dimensional crystals are described and various methods of characterizing these crystals are summarized. Recent experimental results on polymer crystals, inorganic chain-like crystals, layered crystals and intercalated layer crystals are pre...

Raman spectroscopy was developed by C. V. Raman (Figure 1) in 1928, but until recently has been plagued by weak Raman scattering responses compared to strong, interfering, Rayleigh scattering, plus fluorescence interferences. Developments over the past 15 years have permitted Raman spectroscopy to become more useful and easier to use. With these developments, forensic analysis by Raman spectros...

The fast and reliable analysis of the natural gas composition requires the simultaneous quantification of numerous gaseous components. To this end, fiber-enhanced Raman spectroscopy is a powerful tool to detect most components in a single measurement using a single laser source. However, practical issues such as detection limit, gas exchange time and background Raman signals from the fiber mate...

Theoretical analysis of Raman scattering spectra (RS) for single-crystal MoS2 sample and atomically thin MoS2 sample consisting from one to few layers was performed in order to explain the change of MoS2 vibrations at transition from a monoatomic layer to a bulk crystal. Experiments have shown that changes of frequencies of the most intensive bands arising from the in-plane, [Formula: see text]...
