NMR spectroscopy of stereoisomers — NMR spectroscopy techniques can determine the absolute configuration of stereoisomers such as cis or trans alkenes, R or S enantiomers, and R,R or R,S diastereomers.[1][2] In a mixture of enantiomers, these methods can help quantify the optical… … Wikipedia
NMR database — (NMR = nuclear magnetic resonance) may refer to: NMR spectra database, a collection of NMR spectra for a large number of compounds NMR database method, a strategy to identify the stereochemistry of certain chiral compounds This disambiguation… … Wikipedia
NMR spectroscopy — Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is the name given to a technique which exploits the magnetic properties of certain nuclei. This phenomenon and its origins are detailed in a separate section on… … Wikipedia
NMR spectra database — Nuclear Magnetic Resonance (NMR) spectra database is an electronic repository of information concerning NMR spectra. The repository can be stored as a complete self contained data set or as an online repository that can be accessed and searched… … Wikipedia
NMR database method — The NMR database method enables identification of the stereochemistry of chiral molecules, especially polyols. It relies on the observation that NMR spectroscopy data depend only on the immediate environment near an asymmetric carbon, not on the… … Wikipedia

Carbon-13 NMR — (13C NMR or sometimes simply referred to as carbon NMR) is the application of nuclear magnetic resonance (NMR) spectroscopy to carbon. It is analogous to proton NMR (1 H NMR) and allows the identification of carbon atoms in an organic molecule… … Wikipedia
Earth's field NMR — Nuclear magnetic resonance (NMR) in the geomagnetic field is conventionally referred to as Earth s field NMR (EFNMR). Note that the same acronym is used for electric field NMR.EFNMR is a special case of low field NMR.When placed in a constant… … Wikipedia
Proton NMR — (also Hydrogen 1 NMR, or 1HNMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to hydrogen nuclei within the molecules of a substance, in order to determine the structure of its molecules.Simple NMR spectra are… … Wikipedia
Benesi-Hildebrand method — The Benesi Hildebrand method is a mathematical approach used in the determination of the equilibrium constant K and stoichiometry of nonbonding interactions. This method has been typically used to study reaction equilibriums that form 1:1 guest… … Wikipedia
