Addition of clay minerals to the culture media of fungi accelerated or increased biomass and melanin formation. Comparison of band locations and shape of the spectra from the melanins with or without clays indicated that no basic alteration occurred in the composition of the melanins from clay ...
Group frequencies are most useful above about 1500 cm-1; below this the absorptions are due to, or are influenced more by, the skeletal vibrations of the molecule. This is the “fingerprint” region, where even similar molecules may have quite different spectra. Many details of molecular ...
Comprehensive Forensic FT-IR Collection Library Listing – 4,286 spectra This extensive library contains materials not only of forensic interest but also for general problem solving and identification of unknown substances in industry and academia. The wide range of items include drugs, clandestine lab...
The μ-IR spectrometer provides reflectance spectra of the selected features of interest and spectral maps of larger areas. With the combined analyses we obtained a comprehensive mineralogical framework for the three HED samples. It was proven that the mineralogical heterogeneity of the HED meteorites ...
A similar problem also appears in the identification of mixed clay mineral structures by infrared spectroscopy. There are also more or less overlapping absorption bands in the infrared spectra for the mixtures of clay minerals. In this paper, the prepared clay mixtures were supposed to partially ...
Raman spectra exhibit unique bands near 200 and 700 cm 1 that are due to tetrahedral SiO 4 in layer silicates and vary depending on the mineral structure. Raman spectra of clay minerals also have unique metal鈥揙H bending vibrations between 840 and 920 cm 1 that provide information about the...
A total of 123 humic acid isolates from terrestrial and marine, mostly North Sea, sources was analysed by Fourier-transform infrared (FT-IR) spectroscopy. The spectra were found to be strongly influenced by co-extracted clay minerals. After treatment with hydrofluoric acid the ash content of the...
We observed a fantastic presentation of foreseeing soil C and N substance utilizing mid-infrared spectra. In a large portion of cases, the expectations of soil N, P, K, S, and few micronutrients are acceptable. Clay minerals, soil water (volumetric and gravimetric water content), and soil ...
A short description of thermo-IR-spectroscopy analysis is given together with some examples of the interactions between hazardous organic pollutants and clay minerals. Self-supported films of organo-montmorillonite and laponite complexes can be heated in a vacuum cell and the IR spectra of the ...
