IMAGING OF COMPLEX NMR SPECTRA

Investigative Radiology, 1983
The Point Spread Function (PSF) in NMR imaging is the result of both the line broadening due to magnet field inhomogeneity and the intrinsic spectrum of the nucleus at resonance. In the case of proton imaging, the line broadening dominates the small chemical shifts and the spectral lines are not resolved.

CNN processing for NMR spectra

Proceedings of the Third IEEE International Workshop on Cellular Neural Networks and their Applications (CNNA-94), 2002
A method to filter 2D NMR spectra against uncertainties arising from experiments and data acquisition machinery is proposed. This is achieved by using a cellular neural network. The method introduced is explained and is applied to filtering of a real 2D NMR spectrum of a protein. >

NMR spectra of some cyanosteroids

Steroids, 1972
Abstract The MMR Spectra of thirty-four cyanosteroids and of thirty-four model steroids are discussed. The chemical shifts of the protons at C-18, C-19 and C-21 are used to study the cyanosteroid structures and the specific corrections Δδ∗ are calculated.

31P-NMR spectra of AP4

Research In Experimental Medicine, 1985
31P-NMR spectra were obtained from adenosine-5'-tetraphosphate under a variety of conditions and the four discernible resonances assigned. The pK-value of the metal-free compound was determined to be 6.4, the pK-value of the Mg2+ complex to be 5.3. The dissociation constant for the AP4 X Mg2+ complex was estimated to be 10(-4) M from the downfield ...

NMR spectra of estrogen catechols

Tetrahedron, 1968
Abstract The NMR of various estrogen catechol derivatives were observed in CDCl 3 and DMSO. The chemical shifts of the aromatic protons permit the ready assignment of structure to isomeric monoderivatives. The reasons for the different chemical shifts of the two aromatic protons in 2-hydroxyestrogens are discussed.

NMR spectra of fluorinated carbohydrates

Carbohydrate Research, 2000
Recent advances in structural and conformational analysis of fluorinated carbohydrates by NMR spectroscopy are reviewed. Characteristic 1H, 13C, and 19F NMR chemical shifts and coupling constants for selected examples are given and the spectral data of a series of fluorinated carbohydrates were collected in continuation of the review of Csuk and ...

NMR spectra of halopermethylpolysilanes

Journal of Organometallic Chemistry, 1974
Abstract Proton NMR spectra were determined for the series X(SiMe2)nX (n = 3, 4, 6 and X  F, Cl, I) and Me(SiMe2)6X. Fluorine-19 NMR spectrafor the fluorosilanes of these series were also determined. The chemical shift of the methyl protons of the SiMe2X group appears at higher field as the chain length increases.
