Inverse Infrared Spectral Deconvolution for Quantitative Analysis of Polymer Mixtures in Scattering Media.

ABSTRACT: Infrared (IR) spectroscopy is a powerful tool for analyzing complex substances. It allows one to identify materials based on their functional groups. Nevertheless, spectral interpretation of composite materials with IR spectroscopy remains a significant challenge for analytical and forensic laboratories, especially if the samples are small, producing significant scattering that complicates the interpretation of IR spectra. Effectively tackling this challenge, we present an innovative IR-based method for nondestructively identifying the individual components within a mixture. Our study focuses on two- and multicomponent strongly scattering homogeneous mixed-composition microspheres filled with organic polymers. The results reveal that our algorithm can (1) reconstruct the pure absorption of
