MAS-NMR at very high temperatures

Solid State Nucl Magn Reson. 2004 Sep;26(2):84-6. doi: 10.1016/j.ssnmr.2004.03.001.

Abstract

We report MAS-NMR experiments at temperatures of approx. 1200 K using a CO(2) laser as the heating device. An internal NMR thermometer based on the (7)Li T1 data of Li(0.24)La(0.54)TiO(3) is used for temperature calibration. Using this setup, temperatures as high as 1191 K could be reached under MAS conditions as confirmed by the melting of Li(2)B(4)O(7) at 1191 K which could be followed by (7)Li-MAS-NMR.
