There r three reasons
1. TMS have all hydrogen equivalent thus it produce singlet
2. All compounds gives NMR signal downfield to TMS
3. It can be easily removed from liquid samples of proteins beccause it is volatile.

What is the difference between NMR and FT- NMR instrumentation?
NMR Spectroscopy Use molecule Structure FT NMR Use Different No. of mass Structure
How do you interpretation a cosy nmr?
cosy is a one of 2D-NMR technique
What is the method which can be used to differentiate sulphuric acid and ethanoic acid?
you can take NMR of ethanoic acid
Returned Mail came back with stamps crossed out and NMR written on the envelope What is NMR?
no mail recepticle
Why does an NH2 signal not show on a proton NMR?
Depending on the solvent used to dissolve the sample NH2 may or may not show up on h NMR. If it is dissolved in D2O (heavy water) deturium will exchange with the protons attached to heteoatoms and the signal will "dissapear"
What range of electromagnetic radiation is used in NMR?
Molecules emit electromagnetic radiation in NMR spectroscopy.
Logging tool for direct determination of permeability?
Nmr is used
What is the difference between NMR and FT- NMR instrumentation?
NMR Spectroscopy Use molecule Structure FT NMR Use Different No. of mass Structure
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 main difference between NMR and ESR?
NMR is nuclear magnetic resonance.it is based for chemical shift.It is used for organic compound is TMS(Tetra Methyl Silane)
How do you interpretation a cosy nmr?
cosy is a one of 2D-NMR technique
When was Journal of Biomolecular NMR created?
Journal of Biomolecular NMR was created in 1991.
What is the method which can be used to differentiate sulphuric acid and ethanoic acid?
you can take NMR of ethanoic acid
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.

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.
How molecular weight determined by nmr spectroscopy?
NMR isn't really used to determine molecular weight in general. It can be done for certain oligomers by, for instance, determining the ratio of end-group protons to protons that only occur in the "middle" of the chain.
