In this paper, we propose a computationally efficient method for peak extraction in proton NMR spectroscopy without any a priori information. This method combines a simple damped complex exponential ...

They remove the need to transport samples to off-site NMR facilities. This instrument offers high-resolution proton NMR, achieving results within just a few minutes and without the need for ...

6,7,8 Figure 5 provides an example of a proton (1 H) NMR spectrum, meaning that only the protons of the ... One of the most common problems encountered in NMR spectroscopy, as mentioned in Table 2, is ...

AD and GF conceived the work. MG-G performed the NMR measurements and data analysis. All authors analysed and discussed the results. MG-G and AD wrote the manuscript with input from all authors. This ...

Moving on, we’ll look at the applications collected on the X-Pulse, and how they cover a wide range of NMR active nuclei that go beyond traditional proton and carbon-13 NMR – such as phosphorus-31, ...

1 H NMR (42.5 MHz, neat) δ 3.45 (q, J = 7.1, 2 H, H-1), 1.36 (s, 3 H, H-2’), 0.60 (t, J = 7.1, 3 H, H-2). The number of proton environments in this compound are three and it can be observed from the ...

All parameters determined by the proton NMR lipoprotein analysis are shown in Table 1. The front page of the automatic report (B.I.-LISA) is shown in Figure 1. Table 1. Listing of all parameters ...

For comparison of sensitivities of spectra from 3.2 mm (thin-wall), 1.3 mm, and 0.7 mm rotors, we calculated the total mass by weighting the empty and full rotors (Supplementary Table 3). The T 2 ′ ...

NMR exploits the magnetic properties, also referred to as “spin”, of certain atomic nuclei to provide information about their immediate environment. Hydrogen nuclei are a popular choice due to their ...

The state of water in cerebral ischemia was studied by using the proton nuclear magnetic resonance (1H-NMR) method. Cerebral ischemia was induced experimentally in Mongolian gerbils by unilateral ...
