    The photoreactivity of single particles with atmospheric interest was studied by using an acoustic levitation system coupled to Raman microspectrometry. Both inorganic and organic single particle phototransformations have been investigated without any surface contact. The Raman microspectrometry has suitably provided the identification, the chemical heterogeneity as well as the formation rates of products. Complex surface limited processes are demonstrated for photolysis of both nitrate-rich and sulfur-rich droplets.

    Confocal Raman microscopy can be used for the direct imaging of the microstructure of fat spreads. A constraint multivariate curve resolution with alternating least squares approach using a fixed set of pure component spectra is a suitable method to extract the spatial distribution information of each individual component present in the fat spread: sunflower oil, water, emulsifier and solid fat. A new normalization method provides semi-quantitative concentration maps, allowing good microstructural comparison.

    We propose a perturbative approach within a non-orthogonal tight-binding model, which allows for a significant reduction of the computational time for calculation of the optical properties of twisted bilayer graphene. The dependence of the optical transition energies on the twist angle is derived from the dielectric function, and the behaviour of the Raman excitation profile of the G band is studied in detail. The obtained results can be used to support the structural characterization of twisted bilayer graphene.

  4. Analysis of the pigments for smoked mural by confocal micro-Raman spectroscopy

    Confocal micro-Raman spectroscopy is adopted to investigate the smoked murals in Mogao Grottoes. Based on the results of smoked fragments, a feasible and reliable smoking experiment was developed to investigate the degradation of the pigments. Vermilion is damaged, while aragonite and calcite are stable during the smoking process.

  5. Pressure-induced Fermi resonance between fundamental modes in 7,7,8,8-tetracyanoquinodimethane

    Fermi resonance between fundamental modes was observed in TCNQ; the relationship of Fermi resonance parameters with pressure was discussed. The frequency separation is considered the reason for the decay of the intensity ratio of Fermi resonance doublets, and this would be another character of anharmonic coupling between fundamental modes.
