[edit] Addition of TMS

I took out the line on adding TMS because most spectrometers now use the residual solvent peaks as references. Also, TMS should be added to the stock solvent, and not added neat to the NMR tube because it will be far too concentrated. --Rifleman 82 10:44, 9 November 2006 (UTC)

Rifleman 82 -- True, but maybe it would be better to say:

If an NMR reference standard (such as TMS) is required, and not already present in the deutrated solvent, this can be added carefully to the sample.

TMS can be added to a nmr sample but only very carefully! Also, you might want to added some other reference e.g. a solid, not just TMS ...

Is your statement above about referencing to solvent peak true for all nuclei e.g. 31P, 19F etc? It is not common but in 31P NMR people can used mixed solvent system e.g. the compound is dissolved in say non-Deuterated THF (i.e. H's will not effect the 31P spectrum) and the D lock is provided by adding a small amount of say D6-benzene.

Removed the tag because the article is notable and encyclopedic. If there are any other concerns they should be raised here first. --Rifleman 82 17:04, 9 November 2006 (UTC)
