Abstract
The vapour pressure and sublimation enthalpy of HPLC-purified C84 have been determined by Knudsen cell mass spectrometry in the temperature range 658-980 K; the temperature-pressure equation is ln(p/Pa) = (-24337±539)/(T/K) + (25.15±0.64), and the mean sublimation enthalpy at 853 K is 202±4 kJ mol-1.
