Abstract

We present a universal fitting equation (FE) for accurately fitting Angle-Resolved Polarized Raman Spectroscopy (ARPRS) data in polar coordinates. Both theoretical and experimental evidence demonstrate that this FE and program can efficiently process ARPRS data from all materials and configurations, greatly improving speed and accuracy for quantitative analysis. Additionally, many intrinsic physical parameters for some unknown samples can be directly obtained through the fitting process, reducing the need for large equipment. This method also opens avenues for ARPRS-related research, including environmental effects on materials, twisted 2D materials, and stress effects. Our work is highly valuable and meaningful for the future study.

期刊介绍： Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
