If conducting a reaction in research and the desired products are known, an NMR can be ran on the sample to determine whether the reaction is complete or successful. There are many other reasons for NMR though like to determine the behaviors of atoms if placed in more or less electronegative environments...

∙ 14y agoNMR spectroscopy, or nuclear magnetic resonance spectroscopy, is one of the methods used by organic chemists to determine the structure of an unknown molecule. The following is a basic summary of some of the information you can gain from NMR spectra.
There are two types of NMR, 13C NMR and proton NMR. The first type will produce information about the different types of carbons in the unknown molecule. Each chemically inequivalent carbon will produce a peak on the NMR spectrum. Carbons involved in or next to certain functional groups will be more deshielded than carbons only forming alkyl groups.
Proton NMR will provide information about the different hydrogens in the molecule. Again, each chemically inequivalent hydrogen will produce its own peak, differing in location based on their proximity to functional groups. Another feature of proton NMR spectra is the splitting that occurs within the peaks. Hydrogens with chemically inequivalent neighbor hydrogens will have a peak that is split into multiple "mini-peaks" based on how many neighbors that hydrogen has. The number of peaks is always one greater than the number of neighbors - so a hydrogen with no neighbors will have one peak, while a hydrogen with three neighbors will have four, and so on. Finally, proton NMR spectra can show the integration of hydrogens, or how many equivalent hydrogens each peak represents, based on the relative height of the peaks.

How do you get proton decoupled spectra of 13C NMR?
There should be a button that lets you do this very easily. There is on a Brukker 400MHz NMR.
What range of electromagnetic radiation is used in NMR?
Molecules emit electromagnetic radiation in NMR spectroscopy.
Is NMR a solvent extraction technique?
NMR stands for Nuclear Magnetic Resonance. It's an analytical/spectrographic technique based on the Zeeman effect.
How does nmr spectroscopy work?
Magnets and sheet
What is the market cap for Nomura Holdings Inc ADR NMR?
As of July 2014, the market cap for Nomura Holdings Inc ADR (NMR) is $24,127,421,698.38.
Is pmr and nmr same?
No, PMR (Pulse Mass Ratio) and NMR (Nuclear Magnetic Resonance) are not the same. PMR is a technique used in mass spectrometry, while NMR is a technique used in spectroscopy to study the magnetic properties of atomic nuclei. Both techniques are valuable in analytical chemistry but serve different purposes.
What is the primary advantage of 3D-NMR over 2D-NMR?
One more D.It's difficult to answer this question exactly, since it's not always necessarily true that 3D NMR is better than 2D NMR (or even than 1D NMR). It really depends on what information you're looking for. In fact, sometimes information that theoretically couldbe used to add an extra dimension is intentionally supressed (example: carbon-13 CP-MAS, where the proton spins are deliberately blasted to decouple them from the carbon nuclei), because the spectroscopist is not interested in that.
