Summary: Anharmonic quantum chemical calculations were used to simulate and interpret the NIR spectrum of caffeine, revealing a highly convoluted nature with numerous overlapping bands beneath the observed spectral lineshape. Combination bands decisively dominate the NIR spectrum of caffeine, with first overtones significant between 6500-5500 cm(-1) and second overtones meaningful in higher wavenumber regions, particularly in the 10,000-7000 cm(-1) region.

Summary: Spectral techniques, including the fusion of visible-to-near-infrared and mid-infrared absorbance, can improve the estimation of soil organic carbon. The use of continuous wavelet transform and optimal band combination strategies contribute to the accuracy of the prediction models. Among the investigated models, the combination of visible-to-near-infrared and mid-infrared using the optimal band combination fusion at a specific scale yielded the best prediction.

Summary: In this study, near-infrared (NIR) spectroscopy and chemometrics were successfully used to detect common adulterants in roasted ground arabica coffee. The technique could discriminate pure samples from adulterated ones, including single and multiple adulterations. Additionally, NIR spectroscopy showed potential for geographical discrimination of arabica coffees.

Summary: The vibrational spectrum of protonated ethylene (H+(C2H4)) in the 2000 to 3500 cm^-1 region is reinvestigated and features that cannot be predicted by harmonic treatments are observed. The anharmonicities that lead to these higher order transitions are explored, and it is found that states with two quanta in the HCH bending vibrations and one quantum of excitation in the two vibrations of the bridging proton in the CH+C plane carry significant intensity in this region.

Summary: Microplastic pollution is a global concern for the environment and human health. In order to assess the potential hazards associated with high concentrations of microplastics, it is necessary to have a comprehensive understanding of exposure concentrations. Infrared and near-infrared microspectroscopies have been used to analyze microplastics in various matrices, and recent advances in technology have allowed for the use of multivariate and machine learning algorithms. This article provides an up-to-date review of the literature on measuring microplastic exposure using infrared spectroscopy and highlights the recent advancements in this field.

Summary: Combining Raman scattering and Raman optical activity (ROA) with computer simulations allows for the characterization of chiral molecules' fine structure and physicochemical properties. This study presents an accurate and simple approach based on three-quanta anharmonic perturbative mode, showing the significance of anharmonic Raman and ROA spectroscopies in understanding chiral molecules' vibrations and calibrating computational models.

Summary: The inclusion of anharmonicity in vibrational spectral analysis is mainly limited to small molecular systems. This limitation is due to the computational costs associated with larger systems and the lack of clear criteria for the identification of resonances. However, recent advances in vibrational perturbation theory (VPT2) have made it possible to handle resonance problems more transparently. This study demonstrates the importance of experimental benchmarking and highlights the mutual stimulation between experimental techniques and computational models.
