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 ...

Cinnamon has high levels of antioxidants, which is the likely reason behind its health benefits. It is obtained from the dried inner bark of Cinnamomum verum (Ceylon cinnamon) and is called as “true” ...

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 ...

Nuclear magnetic resonance (NMR) spectroscopy was developed to detect protons, and has since then been applied in studying the molecular structure of proteins, RNA, DNA complexes, and interactions ...

NMR spectroscopy enables non-invasive characterization of microstructure properties in nanoemulsion formulations, enhancing excipient selection and formulation optimization. The method supports FDA's ...

It’s an open secret that organic chemistry students struggle to learn a skill that is integral to the field: interpreting nuclear magnetic resonance spectra. Organic chemists use this important tool ...

Nuclear Magnetic Resonance (NMR) was first experimentally observed in late 1945, nearly simultaneously by the research groups of Felix Bloch, at Stanford University and Edward Purcell at Harvard ...

Therapeutic oligonucleotides (ONs) offer promising treatments for conditions beyond what traditional therapies can target. As a new class of molecules, they demand precise characterization in both ...

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 ...
