Application of Computational Chemical Shift Prediction Techniques to the Cereoanhydride Structure Problem-Carboxylate Complications. [PDF]

open access: yes, 2017
Despite the vast array of techniques available to modern-day chemists, structural misassignments still occur. These misassignments are often only realized upon attempted synthesis, when the spectra of synthesized products do not match previously reported

Presence of 3d Quadrupole Moment in LaTiO3 Studied by 47,49Ti NMR

open access: yes, 2003
Ti NMR spectra of LaTiO3 are reexamined and the orbital state of this compound is discussed. The NMR spectra of LaTiO3 taken at 1.5 K under zero external field indicate a large nuclear quadrupole splitting.

Synthesis of Substituted Phenyl N-(2-hydroxybenzyl)-N-Methylcarbamates

open access: yesMolecules, 2002
Thirteen previously unreported substituted phenyl N-(2-hydroxybenzyl)-Nmethylcarbamates were prepared by the reaction of substituted 2-hydroxybenzyl-Nmethylamines with phenyl chlorocarbonates. They were identified by their 1H- and 13C-NMR spectra.

Synthesis and characterization of 2,3,13,14-tetramethyl (ethyl or p-tolyl)- 1,4,12,15-tetraazacyclodocosa-1,3,12,14-tetraene complexes of Mg(II), Ca(II), Sr(II) and Ba(II) [PDF]

open access: yesJournal of the Serbian Chemical Society, 2002
2+2 Cyclocondensation of 1,7-diaminoheptane with α-diketones, viz 2,3-butanedione, 3,4-hexanedione or 4,4’-dimethylbenzil, in the presence of Mg2+, Ca2+, Sr2+ and Ba2+ ions as templates yields a series of complexes of the type [ML(X2)](where L = N4 ...

Laser-induced splittings in the nuclear magnetic resonance spectra of the rare gases

open access: yes, 2004
Circularly polarized laser field causes a shift in the nuclear magnetic resonance (NMR) spectra of all substances. The shift is proportional to the intensity of the laser beam and yields oppositely signed values for left- and right-circularly polarized ...

www.nmrdb.org: Resurrecting and Processing NMR Spectra On-line

open access: yesCHIMIA, 2008
NMR spectroscopy is certainly the analytical methodology that provides the most information about a molecule but the long-term vision of this information is often lacking. We present here two innovative tools accessible free from the web.
