Editing of H2BC NMR spectra [PDF]
Magnetic Resonance in Chemistry, 2005 AbstractNew versions of the H2BC pulse sequence (Nyberg NT, Duus JØ, Sørensen OW. J. Am. Chem. Soc. 2005; 127: 6154) that edit into two subspectra according to the number of protons attached to 13C nuclei being odd or even are introduced. These sequences can be useful for resolving spectral overlap, which is demonstrated on the molecule prednisolone ...

Baseline correction for NMR spectroscopic metabolomics data analysis. [PDF]
, 2008 BackgroundWe propose a statistically principled baseline correction method, derived from a parametric smoothing model. It uses a score function to describe the key features of baseline distortion and constructs an optimal baseline curve to maximize it ...

Composition of Ni2+ cation solvation shell in NiCl2–methanol solution by multinuclear NMR [PDF]
, 2011 1H-, 2H- and 13C-NMR spectra have been used to test the Ni2+ solvation shell composition in the 1.1 molal methanol solution of NiCl2. It has been confirmed that Cl− anion takes part in the nearest environment of Ni2+ cation at all the temperatures ...

Iterative Deconvolution of Quadrupole Split NMR Spectra [PDF]
, 2013 We propose a simple method to deconvolute NMR spectra of quadrupolar nuclei in order to separate the distribution of local magnetic hyperfine field from the quadrupole splitting. It is based on an iterative procedure which allows to express the intensity
