Instrument's Description

The Nuclear Magnetic Resonance spectroscopy is vital for both organic and inorganic chemists for structure elucidation on a routine basis and to follow reactions and dynamic chemical events on a real time scale.

Sample Description
The sample must be sufficiently soluble in a deuterated solvent to yield an NMR spectrum.
 For 1 H NMR, it is recommended to dissolve between 2 and 10 mg in 0.6 to 1 mL of solvent so that the sample depth is at least 4-4.5 cm in the tube.
 For 13 C NMR between 10 and 50 mg of sample is recommended.
 Too concentrated a solution sometimes leads to lower resolution. If sample or solubility is limited, it may still be possible to obtain a spectrum on the 500 MHz spectrometer. The choice of solvent is dictated by various factors such as viscosity, spectral interference, boiling point, and, of course, cost.
