NMR spectroscopy

Question 1

Give reasons why TMS is used as a standard in carbon NMR

Answer 1

It generates one sharp peak
It is unreactive so wont affect the sample being analysed
It is highly volatile so can be removed from the sample after analysis very easily
Peak always found on the far right of the spectrum

Question 2

what solvent is used in proton NMR and why

Answer 2

solvents using deuterium such as CDCl3
solvent wont produce any peaks of its own and will not interfere with the analysis.
