Attenuated Total Reflectance Infrared Spectra of Carbonate Minerals, Deconvoluted by Means of q-BWF Functions

International Journal of Sciences, 2024, vol. 13, issue 09, 76-83

Abstract: Here we consider some carbonate minerals and their attenuated total reflectance (ATR) infrared spectra, that we can find in RRUFF database. We apply the q-BWF functions to deconvolute the components of the spectra. The q-BWF functions are the asymmetric line shapes that A. C. Sparavigna defined in 2023, to generalize the BWF (Breit-Wigner-Fano) functions. Nearby all the ATR spectra that we will consider are characterized by the presence of a large peak. We will show that, in the case of aragonite and bastnäsite-(Ce), only one q-BWF function is enough for fitting this main peak.
