Abstract

A method for temperature calibration of CP/MAS NMR probes and their temperature controllers is described that relies upon known phase changes in the compounds adamantane, d-camphor, pivalic acid and DABCO. The method appears to give a convenient and reliable calibration over the temperature range ca. 173-373 K. In a separate experiment, making use of a well defined lineshape coalescence, it was shown that the temperature effect of spinning in a 4 mm Bruker MAS probe with zirconia rotors could be fitted by a squared relationship but that if treated as approximately linear the variation was ca. 1 K kHz-1.
