Spectral harmonization of Raman data for reliable anti-counterfeiting analysis
Authors: María Fernández-Álvarez, Alberto Moure, Pablo Rabasco, Esther Gómez, Vicente García-Juez, José Francisco Fernández
The main objective of this work is to establish a feasible approach to harmonize different Raman systems to enable the comparison of Raman spectra within the context of counterfeit detection. The goal is to ensure that different Raman systems produce equivalent results, thereby fostering interoperability among Raman instruments.
Impact of Beam Profile on Raman Spectroscopy Measurements

Advanced spectroscopic characterization of calcium carbonate polymorphs: Ab initio dynamic approaches and experimental Raman
Authors: Fileto Rodríguez, Robin Francotte, Beata Taudul, Jianing Wang, Ionut Tranca, Diane Sorgeloos, Enrique Lozano Diz, Monica Calatayud, Frederik Tielens
Our findings lead the way for the accurate computation of vibrational spectra in materials where anharmonicity, temperature or conformational variety have a considerable impact in the resulting spectrum. This work represents a step forward in accurately modeling and interpreting the spectroscopic behavior of ionic materials, pushing the boundaries of computational materials science.

Open Source for Raman Spectroscopy Data Harmonization
Authors: Georgi Georgiev, Dirk Lelinger, Luchesar Iliev, Vedrin Jeliazkov, Miguel Banares, Raquel Portela, Nina Jeliazkova
Raman spectroscopy is becoming a key technology used in the research and development for characterization of materials. Ideally, spectra should be comparable and linked to specific material properties. However, in real life, Raman spectra differ between instruments and depend on the spectrometer, optical path, or sample environment, among others, and only a limited number of calibration standards for Raman spectroscopy are available to date.
