== Overview ==
The complex refractive index is a basic property in the study of light-matter interactions and spectroscopy. Especially in the sum frequency generation (SFG) vibrational spectroscopy studies, the analysis of SFG spectra requires detailed information of the Fresnel factors in the typical three-layer interface model. Studies <ref name = "ref1" /> have shown that the dispersion of the Fresnel factor may become significant and seriously change the analysis results of SFG spectra. The dispersion of Fresnel factors in SFG spectra originates from the complex refractive index of the liquid. However, the complex refractive index in the Infrared region is somehow unavailable for most commonly used liquids in SFG studies. Therefore, we have developed ComplexRI software package to obtain the complex refractive index of any liquids by using the ATR-IR spectra. The output of ComplexRI is the complex refractive index in IR region. Users can specify the target vibrational regions.
==Developing History==
The development of ComplexRI was done by Lin Wang, Ryo Murata, Teppei Kamimura, Akihiro Morita in the lab of computational molecular science at Tohoku University.
The main code was first developed by Wang in 2019 when he investigated the dispersion of Fresnel factor in electrode/electrolyte interfaces. <ref name = "ref1" /> In 2020, Murata and Wang further extended the code and generated a complex refractive index database with about 20 commonly used liquids in SFG studies. <ref name = "ref2" /> Wang used the database and discussed the general influence of dispersion of Fresnel factor in the SFG spectra analysis. <ref name = "ref3" />. In 2021, the program code was summarized and opened to the website by Kamimura under the supervise of Wang and Morita. The automatic fitting procedure is updated. Kamimura and Wang also created the MediaWiki manual page for ComplexRI.
Many thanks to the experimental collaborators during the development.
