Welcome to NMR-Solvents - Online !!

Solvents used in NMR- spectroscopy are organic liquids of low viscosity and good solubilizing ability. To prevent overlapping by strong solvent signals in the 1H- NMR- spectroscopy protons need to be exchanged by deuterons. In addition the deuteron resonance serves as lock- signal for the stabilisation of the spectrometer. Common solvents are available in different degrees of deuteration:

 

Degree of deuteration [%] 99 99.5 99.8 99.95
Remaining concentration of protons [mol/l] 0.1 - 0.06 0.05 - 0.03 0.02 - 0.01 0.006 - 0.003
Advisable concentration of substance [mol/l] 0.1 0.05 0.02 0.005
