Figure 4. FTIR Spectroscopy functional group correlation table Near-IR Spectroscopy The Near-IR portion of the electromagnetic spectrum falls between 4,000 to 12,800 cm-1. This region consists of overtones (two of the same vibrational modes occurring simultaneously) and combinations (two different ...
Webinar Roundtable Article: Microbial Characterization, Identification and Typing Using FTIR Spectroscopy Polymer analysis Understand what chemical properties you need to control when designing new materials. Advanced features allow you to catch changes in additive formulations, spot degradation of multi...

S4 and Table 3). The chemical bond's characteristic wavelength was found in the FTIR spectra. The IR absorption spectra are used to identify these chemical bonds in a molecule. Fourier-transform infrared spectroscopy is used to analyze the functional groups of Calotropis procera plant extract. ...
Therefore we do not simply have a “look up” table to say what a particular band of energy will absolutely belong to. The spectrum must be interpreted as a whole system and therefore probably demands the most experienced analysts in all of the spectrographic techniques in correctly ...

The composted OWP had in general lower percentages of mineralisable carbon (Cm3-91) as well as lower C/N ratios than the non-composted ones due to the organic matter degradation that took place during the composting phase before soil incubation (Table 1). Meanwhile, a higher mineralisable ...
