[Question from NMRWiki Q&A forum] High Pressure NMR Samples
High Pressure NMR Samples
I need to run NMR on samples of anhydrous ammonia. The boiling point of anhydrous ammonia is -33.34 deg C. In order to be able to have enough time to acquire spectra, I would like to seal the NMR tubes. Once the sample tubes are sealed, the ammonia will build up pressure until it reaches equilibrium and exists as a liquid at room temperature (at approximately 10 atm of pressure). I know NMR tubes exist which can easily withstand these sorts of pressures, but my main problem is in finding a way to seal the tube. I have tried sealing the tubes by melting the...

Biochim Biophys Acta. 2004 Sep 24;1674(2):182-92
Authors: Corda M, Era B, Fais A, Casu M
The potentiality of xenon's sensitivity to its local magnetic environment is thoroughly investigated to probe internal structural differences between pig and horse metmyoglobin (MMb). These MMb's differ by 14 amino acids. One of these, Ile142 in horse MMb, is located in the proximal cavity, which...

J Biomol NMR. 1998 Nov;12(4):535-41
Authors: Inoue K, Yamada H, Imoto T, Akasaka K
The effect of pressure on the structure of gurmarin, a globular, 35-residue protein from Gymnema sylvestre, was studied in aqueous environment (95% 1H2O/5% 2H2O, pH 2.0) with an on-line variable pressure NMR system operating at 750 MHz. Two-dimensional TOCSY and NOESY spectra were measured as functions of pressure between 1 and 2000 bar at...
