Solvated Silylium Cations: Structure Determination by NMR Spectroscopy and the NMR/Ab Initio/IGLO Method
Sixty R3SiX/solvent (S) and R2HSiX/S systems with R ) methyl, ethyl, butyl and S ) methylene chloride, DMPU, DMSO, sulfolane, HMPA, acetonitrile, pyridine, N-methylimidazole, and triethylamine were investigated with the help of NMR spectroscopy for different concentration ratios of R3SiX/S and R2HSiX/S as well as different temperatures. With the help of measured δ29Si and δ13C chemical shifts a...
متن کاملThe measurement of droplet size distribution of water-oil emulsion through NMR method
The effects of water/oil volume ratio, type and concentration of demulsifier, water salinity and mixing speed on the average water droplets size in water-oil emulsion are evaluated at different times through NMR measurements.The type and concentration of demulsifier have the greatest effects on the average droplet size with 38% and 31.5%, respectively. The water/oil volume ratio, water salinity...
متن کاملFilter diagonalization method for processing PFG NMR data.
Obtaining diffusion coefficients from PFG NMR diffusion (a.k.a DOSY) data is, in the general case, an ill-posed problem. Numerous methods for processing such data have therefore been developed, each with different constraints and assumptions. The Regularized Resolvent Transform (RRT) is a proven and robust method for spectral inversion. In earlier papers RRT, albeit very slow, was argued to be ...
متن کاملPICKY: a novel SVD-based NMR spectra peak picking method
MOTIVATION Picking peaks from experimental NMR spectra is a key unsolved problem for automated NMR protein structure determination. Such a process is a prerequisite for resonance assignment, nuclear overhauser enhancement (NOE) distance restraint assignment, and structure calculation tasks. Manual or semi-automatic peak picking, which is currently the prominent way used in NMR labs, is tedious,...
متن کاملA single-scan method for NMR 2D J-resolved spectroscopy.
A single-scan method is proposed to shorten the acquisition time for an NMR 2D J-resolved spectrum to 1 second. With high SNRs and acceptable resolutions, it constitutes an effective tool for obtaining decoupled proton spectra and fine scalar-coupling splitting patterns.
