Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique used to identify and quantify the constituents of complex mixtures. Each nucleus of an atom which has a non-zero spin quantum ...

Unfortunately, many 1H-NMR spectra are severely overlapped due to the multiplet structure caused by homo-nuclear scalar couplings. "Pure shift" NMR spectra, also known as broadband homonuclear ...

Please prepare your samples in the designated area or under a hood, and not on top of the magnet. The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the ...

Since those early days, NMR spectroscopy progressed concurrently with advances in many other fields, such as mathematics, physics and informatics. In the 1960s, the implementation of superconducting ...

Nuclear magnetic resonance (NMR) spectroscopy is a research technique that exploits the magnetic properties of atomic nuclei to determine the chemical and physical characteristics of the molecules or ...

Botanical extracts are valued for the perceived benefit derived from their natural compounds. These extracts are major ingredients in personal care products and nutraceuticals. These industries are ...
