Nuclear magnetic resonance (NMR) spectroscopy: Basic.
Environmental chemistry research Our research group studies environmental processes at the molecular-level. We use advanced analytical tools (namely mass spectrometry and nuclear magnetic resonance spectroscopy) to understand the structure and environmental reactivity of natural organic matter found in soils, sediments, water, and ice.

NMR spectroscopy has played a central role in the development of the field of natural products by providing an extraordinary diverse range of applications. This Special Issue will provide a platform for publishing original research papers, short communications or reviews in the following contemporary applications of NMR.
Totally, 33 metabolites were unambi- guously identified based on the NMR spectra, allowing us to address metabolic changes in the HUVEC cells at different passages. At first, the PCA analysis of the five groups of cells was performed to obtain a comprehensive comparison of metabolic profiles in HUVECs during replicative senescence.
Infrared Spectroscopy. Infrared Spectroscopy is the type of spectroscopy that involves in the infrared region of the electromagnetic spectrum that is mild with a longer wavelength and diminishes frequency than seen gentle. It covers a variety of procedures, frequently situated on absorption spectroscopy.
The procedure was verified for mixtures of triacylglycerols (vegetable oils) and methyl esters of oleic, linoleic and linolenic acids as well as palmitic and stearic acids. Generally, the NMR (400 MHz) results were in good agreement with gas chromatographic (GC) analyses.
NMR spectroscopy can provide residue-specific information on structure, dynamics and interactions that is complementary to information from other biophysical methods such as crystallography, cryo-EM, small angle X-ray scattering and calorimetry.
