The chemical shifts (d) of solvent signals observed for 1 H NMR and 13 C NMR spectra are listed in the following table. The multiplicity is shown in parentheses as 1 for singlet, 2 for doublet, 3 for ...

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 ...

This magnetic field makes the possible spin-states of the nucleus differ in energy, and using NMR techniques the spins can be made to create observable transitions between the spin states. Common NMR ...

A deep learning framework (NMRNet) is developed to model atomic environments for predicting NMR chemical shifts. A benchmark dataset, nmrshiftdb2-2024, is also established to provide a ...

Building on the success of its 1.0-1.2 GHz systems, Bruker's 1.3 GHz NMR spectrometer offers unprecedented resolution and ...
