Students sometimes ask whether or not they can collect NMR data during a liquid helium refill. The answer depends on the type of NMR experiment. For most solids experiments, where high resolution (

[U. of Ottawa NMR Facility Blog] Resolution During a Liquid Nitrogen Refill
Resolution During a Liquid Nitrogen Refill
Just as it is not advisable to collect high resolution NMR data during (and shortly after) a liquid helium refill, it is similarly not advisable to collect data during a liquid nitrogen fill. The figure below illustrates this point. A 300 MHz NMR spectrometer was set up to collect an NMR spectrum every minute before, during and after a liquid nitrogen refill. The resolution deteriorates as soon as the one-way valves are removed from the nitrogen cryostat. One can see that the resolution during the fill is much worse than before the fill. Even 60...

Many of the difficulties presented by large, aggregation-prone, and membrane proteins to modern solution NMR spectroscopy can be alleviated by actively seeking to increase the effective rate of molecular reorientation. An emerging approach involves encapsulating the protein of interest within the protective shell of a...
