Use our NMR service that provides 14 N, 15 N-NMR and many other NMR techniques. We recommend 1 H-15 N heteronuclear correlation as a more sensitive alternative to 15 N-NMR in most cases. Nitrogen has two NMR active nuclei (fig. 1). …

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.

15 N NMR spectroscopy is applied on natural products organic and organometallics compounds, heterocycles, and biomolecules such as peptides and proteins. 15 N-labeled compounds are widely used due to its inherent low sensitivity.

2021年11月11日 · Successful monitoring of the ortho-selective nitration of aniline has been demonstrated using the 14 N NMR protocol developed in this paper, which will help realize the visualization of nitration processes in the industry.

2022年8月28日 · Nuclear magnetic resonance spectroscopy (NMR) is a widely used and powerful method that takes advantage of the magnetic properties of certain nuclei. The basic principle behind NMR is that some nuclei exist in specific nuclear spin states when exposed to …

2023年1月30日 · Nuclear Magnetic Resonance (NMR) is a nuclei (Nuclear) specific spectroscopy that has far reaching applications throughout the physical sciences and industry. NMR uses a large magnet (Magnetic) to probe the intrinsic spin properties of atomic nuclei.

Recently, liquid and solid state 15 N NMR has become a powerful tool for determination of chemical structure of humic substances. The 15 N NMR spectra of humic substances show evidences of the presence of quinones, ketones, and esters. Also it shows that most of the nitrogen occurs in amide forms.

2023年1月30日 · Nuclear Magnetic Resonance (NMR) interpretation plays a pivotal role in molecular identifications. As interpreting NMR spectra, the structure of an unknown compound, as well as known structures, can be assigned by several factors such as chemical shift, spin multiplicity, coupling constants, and integration.
