“…Despite some limitations, analysis with this technique is ideal for forensic examiners due to the instrument's ability to analyze samples with minimal preparation prior to examination, creating a shorter time frame for analysis and faster results. 135 Owing to its ability to differentiate organic chemical structures that contain the same atoms but vary in arrangement, several studies have recently examined the possibility of using Raman spectroscopy. 136 For analyzing soil fertility and nutrient content in China, Xing et al sought to determine soil organic matter through Raman coupled with Fourier transform infrared photoacoustic spectroscopy (FTIR-PAS).…”

“…This method was found to be limited in its capacity to distinguish among overlapping spectral bands caused by the vibrational coupling of chemical bonds. Despite some limitations, analysis with this technique is ideal for forensic examiners due to the instrument’s ability to analyze samples with minimal preparation prior to examination, creating a shorter time frame for analysis and faster results …”

“…The method of the IR spectroscopy makes it possible to study not only the electronic and spatial structure of hydrated minerals, but also to perform a quantitative analysis of the mineralogical composition of soils [7,8]. The results of studying the IR spectra of clay soils make it possible to calculate a wide range of mechanical properties, including plastic properties and characteristics of shrinkage and tension [9].…”

The hydration of the basal surfaces of kaolinite is studied by theoretical methods. The cluster method was used to simulate the positions of atoms. The positions of the atoms of the basal surfaces of dry and hydrated minerals are optimized by minimizing the total energy in the Hartree–Fock approximation. The adsorption energies of water molecules were calculated taking into account the fourth-order correlation corrections of Møller–Plesset perturbation theory. The formation of the IR spectrum of kaolinite in the range of wave numbers 2500–4500 cm−1 is studied. The experimentally observed effect of the change in relative intensity and position of the band with a change in the moisture content of the sample is interpreted.
